Custom text over bar chart.

[BurhanMughal]

Hi Daniel,
Hope you are doing good.

Can we show our custom value/Text over every bar in Bar chart ?

Currently : Bar value is shown above bar.
Expected Behavior: Show custom value/text over every bar.

Thanks.

[BurhanMughal]

Waiting for positive reply

Use a custom number formatter

[BurhanMughal]

I think you didn't get my point.

Data values are something like this : 105,115,120,129,154 etc.

I have type against every data value i.e. Walking,Running,Cycling etc.

I want to draw graph on the bases of values and draw my type over each bar.

I think I have explained much.

[danielgindi]

I didn't quite understand you.

[BurhanMughal]

Well this is what I am looking to achieve.
Thanks.

[danielgindi]

Still you can use a custom NSNumberFormatter. You will receive the value
that you need - and output a String...

I think I can only pass two arrays i.e. xAxis and yAxis containing numbers. How can I pas number and string simultaneously ?

[danielgindi]

Well you do not pass a String. You said you do not want the value to show,
only a String right?
If so - then you can use a custom NSNumberFormatter - that will return your
custom String per value.
If you want to show both numeric value and a custom String - that's a
different case that we would have to consider.

Sorry I couldn't quite get your idea, If it will return my custom string not value then how the graph will be populated ?
Getting confused.

[danielgindi]

The charts are populated with real values. The NSNumberFormatter is used to
generate the Strings that are rendered on the chart.

Neither. When I say custom NSNumberFormatter, I mean custom
NSNumberFormatter.

Should I modify ChartViewBase or ChartRenderer ?

Subclass the damn thing. You should really read some of Apple's
documentation on their APIs.

I solved it.. Thanks for your support. I just made changes in swift code and it works fine :) 👍

[danielgindi]

That is not the correct approach, as updated to the project will keep coming. There are APIs for almost anything, and standard ways to customize things.

[BurhanMughal]

Yes you are right, It will take some time to apply your suggested approach and I can't afford time loss at this moment that's y I did this. Thanks anyway for suggestion I will eventually apply that one.

Regards.

[BurhanMughal]

I found it ultimately Daniel, there are two methods for init the BarDataEntry object one is without data and other one with additional (id) data __nullable parameter. I just populate my custom text in that parameter against each data entry and use it in drawText method in BarChartRenderer :).
