How to add custom text to the diagram

[SvenMuc]

Hi,
I'm currently trying to adde custom text within the bar chart diagram. What's the best way to do so?
Are there already some internal functions available?

Thanks for you support

It depends on what text you want to add and where. There is labels, values text, and ChartMarker to let you display some custom text when you tap the bar; of cause you could write your own code to display the chart markers when the chart is loaded.

I'd like to plot three histograms into one diagram and add a text field (description) above each bar chart. It is just a label which I'd like to position at any place in the diagram.

I saw a function called drawExtras . Is that the right place to add custom drawings?

Hi, attached you can find an example what I'm planning to do.

Alternatively, I'm also thinking about groups at the x-axis, like Excel does.

Technically, as long as you know how it works, you can draw whatever you like on the canvas. Just keep it easy for you to maintain if any version upgrade;

There is legend, chart marker, here for you. But looks like you need to override and calculate the right position. For ultimate flexibility, I would consider create a chart marker; Anyway, just pick one you feel comfortable to use.
