I am trying to build report using Telerik report designer and not able to identify if charts in below format are supported, if supported which chart type we have to use and which property will fill in color between low and high
candlestick , range chart only displays lines (2nd image)
For the candlestick, it looks like a configuration issue. Please, check these things:
High, Low, Open, Close are not properly set
The data source fields that are used are not of numeric type (i.e. hold numerics as strings)
As for coloring the candlestick, check DataPointStyle property. there you can either set BackgroundColor directly, or use DataPointConditionalFormatting in order to add dynamic formatting based on the underlying data.
I am not sure what is the chart in the first picture, can you please shed some more light on its purpose?

I have 2 questions need your help.
I would like to add a button on each plot to be a setting button. I use label with event listener and it works well ( as shown in attached file). However, my client asked me to change from normal text to graphic icon? How should I proceed?
As you can see from the attached image, the third plot is macd series. The value rage is from -3e-8 to 3e-8 (by my observation). I manually set the maximum and minimum, and it get incorrect scale as shown.
How should I set the maximum and minimum for yScale?
I don't know how to get maximum and minimum value from a series. Can you suggest me?
A1 – Unfortunately, the current version of AnyChart doesn't provide an opportunity to add custom-made buttons inside the chart. But you can use a trick and use stage based layout. It means that the container includes a stage. The stage includes the stock chart all other elements by layers. Using this approach you can place an image (icon) upon the plot and set a listener just as for the 'settings' label.
For details, please, check the sample in the comment below.
A2 - We are planning to fix this behavior in 8.4.2 update (approximately by the end of November 2018).
I will notify you when the fix becomes available.
As a temporary workaround, you can get min /max value from your MACD indicator. For details, please, check the sample in the comment below.
You can apply min/max to the yScale of plot #0 like this:
chart.plot(0).yScale().minimum(minValue);
chart.plot(0).yScale().maximum(maxValue);
We are glad to inform you that we have released 8.4.2 update which brings many fixes and improvements. This update also includes a fix on the issue you reported. Now calculation of min/max of Y-scale works properly with small values. Update your binaries to get the fix.
I have a classic report in my APEX app. I need to do something like conditional formatting in Excel - to change background color of cells in one column, based on the value of the cells. I found some tutorials, but all for interactive reports, which didn't work with the classic report. Can anybody help me with that issue?
If you're trying to conditionally color entire rows, you'll probably want the built-in alternative row templates with conditions. It's part of the report template.
But if you want to format individual cells, the usual way of doing it is to calculate the background color you want in a new SQL column, hide the column, then get the color value using a #COLUMN_NAME# substitution variable. See this article for a simple example, but there are a lot of other examples if you just search for apex conditional cell formatting.
I am trying to make the series name in a bar chart show up as a Data Label in spreadsheetgear 2012 but cannot find a way to make it visible in the chart explorer. Any help would be appreciated.
While the ChartExplorer allows you to modify many aspects of a chart, it does not yet support modifying data label related chart elements.
Instead, you'll need to use SpreadsheetGear API to do this, which would involve enabling ISeries.HasDataLabels and then fine-tuning how the labels are displayed with ISeries.DataLabels (see IDataLabels interface). Example:
// Assuming you have an IChart object named "chart", enable
// data labels for the first series.
chart.SeriesCollection[0].HasDataLabels = true;
How can I achieve this kind of grid? What controls/tools I should use? Any idea?
This screen cast is from the Baplie Viewer application. I guess it was done by the captain using visual foxpro while he was sailing.
[Edit]
It is ready-only and column widths will be fixed. It is a kind of reporting generated in a tabular format similar to Grid, but I think we cannot use the native Grid control.
And it may be needed to generate dynamically. I mean we would not be able to use shape tools, line tool, etc. in design time.
Is the grid editable? Or readonly?
A VFP grid control can take any of the VFP controls as the column control source. For example, the "Total" row may be two columns. The second column could contain another VFP grid as it's control source. While the first column is just a textbox or label.
Or, this grid could be readonly and created by using the Line or Shape controls, coloring their areas and using labels to represent the data.
If you are interested in using third party controls like this, I would recommend DBI-Technologies. They have a large selection of custom controls that work with VFP.
That's not a grid control, or a FoxPro control of any type. (Or, at least, that's not the best way to get that effect.) It's a webview control bound to an HTML web page, generated in the background and then displayed most likely via a temporary file.
The easiest way to achieve the effect in a FoxPro application is to use the CUROSRTOXML function and a XSLT transformation.
I would like to highlight a single value on an axis; similar to the way that stock charts display the live price on the axis.
You could use an annotation tool to show a textbox with the value and a color line tool if you also want to have vertical/horizontal line highlighting the value. However, both tools are only available with the Pro version, and these are two features that would be quite easy to achieve with custom drawing techniques at OnAfterDraw event.
