When a chart is created with legend, automatically legend interactions will be enabled. So user can tap on a legend item to hide/show a respective series in chart.
My requirement is, by default few series in chart should be hidden and respective legend items should be shown as grayed(hidden in legend). So programatically, i should be able to hide those series and set respective legend items as grayed.
How i can achive this functionality? Please let me know, what APIs I can use to achive this.
There really isn't an interaction or event. You can hook into Ext.chart.series.Series#hideAll and showAll to seta n attribute to the legend item.

In react-native-chart-kit Pie chart is there any property or modification to set legend like this?? and also click to show tooltip ?.
I had the same problem, and I have set haslegend={false} and shown this data in the view from the array.
I need to customize the placement of a vertical axis label on a horizontal stacked bar chart in Excel. Currently I can only place the axis label outside of the chart, but I need to show each label inside the chart - to the left or right of the bar it is associated with (depending on orientation).
The easiest way to do this is to add a text box that references the cells that contain the title values. This is much easier than customizing the chart titles themselves.
According to our needs, we need to show the x-axis information at the top and bottom of the chart, how to show more x-axes? THX
Several of the Core Plot example apps show how to add multiple axes in a graph. See, for example, the "Axis Demo" in the Plot Gallery app. Position one x-axis at the top and the other at the bottom using the axisConstraints or orthogonalCoordinateDecimal.
I am creating a program which given some data files, creates charts based on these files. Rather than creating multiple charts, I have chosen to create multiple chart areas in a loop and add the various data to the chart areas. When using some sample data, which is small, the program creates 3 chart areas within a chart and works fine.
However using larger data, the program creates the chart areas but because there are over 10 chart areas to create, they do not fit into the size of the chart and also are aligned vertically rather than horizontally.
What I would like to do is increase the size of the chart fitting in all the chart areas for large data, aligning all the chart areas vertically and allowing the user to view all the chart areas via a scroll bar, since there will be a lot of chart areas using the real data files, any help will be appreciated.
The below are examples of alignment types you can switch to
Chart1.ChartAreas(0).AlignmentOrientation = AreaAlignmentOrientations.Horizontal
Chart1.ChartAreas(0).AlignmentOrientation = AreaAlignmentOrientations.Vertical
As for a scroll bar, the chart control doesn't support scroll bars. What I would do is have my original chart contained in some sort of panel/tab [any container that supports scroll bars] and then is number of charts required reaches a certain level add another chart below your original and then allow the container to build the scroll bar
'when charts required is now 5 create new chart
If Chart1.ChartAreas.Count =4 Then
Dim OverflowChart As New Chart
'add a new chart below your current chart and let the container
'have the scroll bar and not your chart control
End if
I managed to figure it soon after I posted here which is ironic. For the sake of anyone with similar problems in the future. The way I did it was to:
- Add a scrollbar to the form
- Make the blank chart as big as possible to fit whatever data which was going to be used
- Manually set the position of each chart area using ChartArea.Position and changing the posY for each chart in a loop
This worked great and gave me a lot of control as to how big I wanted the chart areas since ChartAreas.Position also has a width and height attribute and allowed me to easily align the chart areas horiziontally using the y coordinates of each chart area.
I am unable to set the label name exact below the bar of bar chart. How to change its origin value to move right side so that it will be exact below of the bar. Please find the image here in this link: i.imgur.com/kJEeM.png
I am search for solution, yet I did not get any solution please help me out of this....
You should use axis labels on the x-axis. There are several example apps included with Core Plot that show how to format dates on the axes. If you already have the text of the labels, you can use custom labels instead. There are examples of that technique, too. The linked image doesn't show an axis line--just set the axis and tick line styles to nil to suppress drawing the axis line.
