I am trying to get max & sum of two columns in a filter expression using MapboxGL-js. The two columns of interest may contain nulls.
Tried this for addition and it does not work (nothing shows up on the map)
["+",["to-number",['get', "col1"]],["to-number",['get', "col2"]]]
For max,I tried this and does not work either.
["max",["to-number",['get', "col1"]],["to-number",['get', "col2"]]]
Any suggestions? Thanks!
The filter defined in mapboxgl-js is
filter is a property at the layer level that determines which features should be rendered in a style layer.
In official mapboxgl-js example you can see that in case condition is true the feature will be rendered:
"filter": ["==", "icon", symbol]
where "icon" is equal to symbol (a variable that is set to the selected feature's icon property).
In your example there are no conditional operation done.
In case you are trying to show the "sum" or "max" as a layer's "text-field", you should use it there and not in filter, and return string after completing your Math operations.
so it will be
"test-field": ["to-string", ["max",["to-number", ["get", "col1"]],["to-number", ["get", "col2"] ]]],

I'm using free jqgrid, I implemented custom search operands using "customSortOperations: {}", I want to change the search field input to a select when I choose one of my custom operands, is there a way to do that? if not is there an event that fires when the operand is chosen to listen for it and implement my custom search field change? here is a sample of how I'm using "customSortOperations: {}"
$.extend($.jgrid.defaults, {
customSortOperations: {
tst: {
operand: "T",
text: "Test",
}
},
});
You posted only short fragment of your code. Thus, I'm not sure that I full understand your problem. To use new custom search operand you should define filter method inside of customSortOperations.tst and include the operation "tst" inside of searchoptions.sopt of column definition in colModel. If you want to use the new operation "tst" as default searching operation then the operation "tst" should be the first in searchoptions.sopt array. See for example https://jsfiddle.net/OlegKi/f3gLde6m/2/ created for the old answer for more details.
Trying to show/hide a couple of rectangles in SSRS based on an expression which uses the value of a parameter in the report. See the screenshots for more details. When the '-Cover pages' label is picked I want it to display the rectangle but I consistently get the following errors. It can't seem to convert and read the parameter expression no matter what I do.
The expression I'm trying to use is:
=iif(Parameters!specparam.Value="-Cover Pages",true,false)
It looks like the label of your parameter is what you're looking for based on the image provided and your expression. Try to switch instead to:
=IIF(Parameters!specparam.Label="-Cover Pages",TRUE,FALSE)
(Note: I switched specparam.Value to specparam.Label.
Your comment is very close. Apply this expression to the Hidden property of the rectangle:
=IIF( Parameters!specparam.Label.Equals("-Cover Pages"), FALSE, TRUE )
You'll notice I have switched around the FALSE and TRUE as you don't want the rectangle to hide when the parameter matches.
Edit:
As you're dealing with a multivalue parameter, you can use a combination of Array.IndexOf and Split to check if your value is one of the selected parameters.
Apply this expression to the Hidden property of your rectangle:
=IIF( Array.IndexOf( Split( Parameters!specparam.Value, "," ), "-Cover Pages" ) > -1, FALSE, TRUE )
Is it possible to search an account's custom data to find a value contained in an array?
Something like:
?customData.[arrayName].{key}=value
The Stormpath docs don't mention array searching.
Yes, with Stormpath it is totally possible to search for custom data even if the values are stored as an array!
Please note that the field names are simple names, and the values are what are different data types like array, map, string etc... so the query is not as complex as one would think :-)
For example, if I want to store custom data called favoriteColors, which is an array like
"favoriteColors": [ "red", "black", "blue", "white" ]
Notice the field name is just like any other field name. The value is the array.
To search for accounts which have a value red in the favoriteColors array, you just need the normal query syntax:
?customData.favoriteColors=red
The full request (if searching a Directory of accounts), might look like this:
https://api.stormpath.com/v1/directories/<directory_uid>/accounts?customData.favoriteColors=red
You could also do the same search on the Tenant resource to search tenant-wide (across all accounts):
https://api.stormpath.com/v1/tenants/<tenant_uid>/accounts?customData.favoriteColors=red
This query would match an account that contains red in the favoriteColors array. If I changed the query to ?customData.favoriteColors=yellow it would not match unless yellow was also added to the array.
Searching for custom data in an array can definitely be done. The syntax is: customData.{fieldName}\[{index}\]=value where {index} can be the specific index you are looking for, or * if you want to find it anywhere in the array. (Note that the [] characters are escaped with a backslash or the query interpreter gets it confused with a range query.)
If you leave off the index entirely, then \[*\] is implied. More precisely, Stormpath will check for either the value in the fieldName or the value as an element in an array of fieldName. However, syntactic sugar can only work if the array field is the last element in your search. Since you can put literally any JSON object into your custom data, Stormpath cannot check every single possibility. Imagine something like customData.foo.bar.baz.qux=bingo. Stormpath would not try to guess that maybe foo is an array, maybe bar is an array or not, maybe baz is an array or not - only maybe qux is an array or not. So, if you want to search an array of objects, you cannot leave out the \[*\].
Here is an example. I have an account with the custom data:
{
"favoriteThings": [
{
"thing": "raindrops",
"location": "on roses"
},
{
"thing": "whiskers",
"location": "on kittens"
},
{
"thing": "snowflakes",
"location": "on my nose and eye lashes"
}
],
"favoriteColors": [
"blue",
"grey"
]
}
The following queries will yield the following results:
customData.favoriteColors=blue will include this account.
customData.favoriteColors\[1\]=blue will not include this account because blue is not at index 1.
customData.favoriteThings\[*\].thing=whiskers will include this account
customData.favoriteThings\[*\].thing=ponies will not include this account because it does not list ponies as one of his favorite things, but may include other accounts with custom data in the same structure.
customData.favoriteThings.thing=whiskers would not include this account or any other accounts with the same custom data structure because in that case, Stormpath would be looking for a single nested JSON favoriteThings object, not an array.
Considering theses xpath expressions :
//*[#id="searchResults"]/div[1]/div[1]/h2/span
//*[#id="searchResults"]/div[3]/div[1]/h2/span
//*[#id="searchResults"]/div[5]/div[1]/h2/span
For your info the div inside search result's class is article searchResult and the one inside article searchResult is header.
I am not sure how to construct an xpath matching all three of the above elements. Is there a tool or a how to guide for that?
Thanks
Use position function
//*[#id="searchResults"]/div[position()=1 or position()=3 or position()=5]/div[1]/h2/span
If, by 'all', you mean all div in even position index, then you can use mod operator to check :
//*[#id="searchResults"]/div[position() mod 2 = 1]/div[1]/h2/span
but if 'all' literally means all, then you don't need index to return all matched elements :
//*[#id="searchResults"]/div/div[1]/h2/span
Pretty straight forward question, as soon as i use setseries data the visibility my pie chart is no longer visible. I have checked the plot object and the series were updated correctly, however since I do not find a visibility attribute anywhere in the plot object, i am at a loss.
The lack of zingcharts documentation and proper examples does not aid either. Im fairly certain this is a simple scenario to solve, but I've been unable to do so.
zingchart.exec('organismplot', 'setseriesdata', {
"data": [
{
"values":data_update.organisms,
"text":"active",
"background-color":"#2d4962",
"border-width":"1px",
"shadow":0,
"visible":1
},
{
"values":(data_update.totalorganism-data_update.organisms),
"text":"passive",
"background-color":"#2d4962",
"border-width":"1px",
"shadow":0,
"visible":0
}]
I'm a member of the ZingChart team, and I'm happy to help you out!
What is the type of data_update.organisms and data_update.totalorganism-data_update.organisms? Make sure that you are passing a single element array, or if those are simply single values, wrap the variables in brackets to create a single value array for the "values" attribute. E.G.:
"data": [
{
"values":[data_update.organisms], // If data_update.organisms is a single value.
"text":"active",
"background-color":"#2d4962",
"border-width":"1px",
"shadow":0,
"visible":1
},
{
"values":[data_update.totalorganism-data_update.organisms], // Again, single value array.
"text":"passive",
"background-color":"#2d4962",
"border-width":"1px",
"shadow":0,
"visible":0
}
]
I've created a demo using your exact method call, except I've changed the "values" attributes to use a single value array, which are needed for pie charts. Check out the demo here.
I hope that helps. Let me know if you need some more help!
