Is it possible to align the data points and outliers of box plot in one straight line like in center of box plot?
Additionally, can I color the data points?
The current and the desired screen shot are attached with it.
You can use
.dataWidthPortion(0)
to not spread the points out at all. Documentation.
General advice on changing the color or style of anything, if there is no accessor for it:
Look for the chart in the chart selectors wiki, or if it's not there, inspect the item you want to change in the developer tools and find out what SVG tag and CSS class the item has. In this case, it's circle.data
Add a pretransition handler which selects the items you want, and changes them:
var cc = d3.scaleOrdinal().range(d3.schemeDark2);
bp02.on('pretransition', chart => {
chart.selectAll('circle.data').attr('fill', function(d) {
const boxDatum = d3.select(this.parentNode).datum();
return cc(boxDatum.value[d]);
})
});
In this case, we're creating an ordinal scale to map the available data to the colors in a color scheme.
The interesting question is here is what data to bind to the color of the dots, and how to get that data.
A box plot's data consists of an array of key/value pairs where each value is a Y value. When the box plot draws it will bind each circle.dot element to the index of the data in the array.
So we need to get the array that is bound to the box. Luckily d3.select(this.parentNode).datum() will give us the key/value pair for the box.
For this example, we are encoding the color based on the Y value, which we get by looking inside boxDatum.value. You don't specify how you want the dots colored but this shows the data that is available.
I am trying to use amCharts and have an interface that looks alot like the step count chart here:
https://www.amcharts.com/demos/step-count-chart/
I want to be able to set the fill color of the column in the middle of the chart. Also when the chart is dragged the color of the columns should change so that it is always the column in the center that has the special color.
Is this possible?
This is Layout I'd like to draw in my ContentPage(ListView is just added)
I tried to use a Grid with a row and two columns in which to place two BoxView inside the first one a further Grid with 3 rows and two columns for the Label in the second Box a Label but the result was disappointing
There are a few options. You can use Grid with Margin and Padding properties so the contents won't be too close to one another. Or you can use AbsoluteLayout or RelativeLayout so you can position every single elements as the way you want to. You can read the documentation for layouts for more information.
New to SlickGrid here, and have a couple questions:
1) Is it possible to change the orientation of the column labels? I would like to display a grid without horizontal scrolling, and the data can easily fit if I limit the width of each column. However is I do that, I dont have enough space for my column labels. So I am wondering if - like in excel - I could change the orientation of the column labels (to say 45 degreees vs. horizontal)? If not, any other suggestion?
2) Is it possible to display D3.js type elements (shapes etc) inside cells? If not, are there options to display things such as color coded stop-lights type things?
As you might have guessed, I am building a dashboard that pulls data from a summary table in a DB, and need visual eye candy. It's probably all doable in D3.js, but I'm looking for a faster way to implement, and a data grid appears appropriate.
I want slickgrid to autosize the columns based on the widest content or header text - whichever is wider. In simpler terms, I want it to simulate the default behavior of regular HTML tables when it comes to column sizing. How can I do it in slickgrid?
When constructing your options, you can use forceFitColumns: true
var options = {
enableCellNavigation: true,
forceFitColumns: true
};
This will make the columns fill the entire width of your grid div.
The OP is looking for columns to grow to match their content. grid.autosizeColumns() grows the cells to fit the parent container, which is not the same thing.
I have added this feature, and it is about as manual as you might imagine. You loop through the displayed cells and measure each one, saving the widest cell and using that width to set the width of your column. SlickGrid gives you good access to the cells in the viewport, so that works nicely.
The measurement algorithm is your big decision. You may put the content off screen and measure it, as #jay suggests. This works, but it is the slowest method, as it requires a repaint to insert, and a repaint when you remove. There may be ways to optimize. The solution I went with is to measure the width of every letter in the alphabet, as well as other typographic characters we come across, and sum them to generate a width. Yes, this sounds absurd. It has many constraints: The font size must be the same, it doesn't support images, there can't be any line returns, and more. If you can live with the constraints though, you can calculate sizes for a huge grid viewport in <5ms, because the character widths are only measured once.
After you get the sizes of the columns, you assign them to your columns using grid.setColumns().
Slickgrid will not support column auto size based on data.You need to write a plugin or fork the slickgrid core to modify.
Here is the link I have created a plugin to handle slickgrid auto size
https://github.com/naresh-n/slickgrid-column-data-autosize
I added this after the grid is drawn and it works fine.
$(window).resize(function() {
var cols = grid.getColumns();
grid.setColumns(cols);
})
You should be able to call the autosizeColumns() method of the grid object.
grid.autosizeColumns();
Make this simple adjustment to Naresh's https://github.com/naresh-n/slickgrid-column-data-autosize, on the init function:
Add $container.ready(resizeAllColumns); to the init function.
This ensures the columns autoresize on initial load
Insert the text into an off-screen element and retrieve the width of the element. This is what excanvas does to measure text. Use this to set the width of the column since it's expecting a pixel value.
