Question

.Net DataVisualization.Charting Formatting values on Y-Axis

Answer 1

+1 A:

You have to set the Format property of LabelStyle in the respective axis.

In your case, like below.

ChartArea.AxisY.LabelStyle.Format = "{0.00}";

Please refer the links below for further details.

Thanks Avatar +1 - that gets me closer to what I'm looking for but not there just yet. That will allow me format a number to x decimal places but it will not allow me to convert the format to fractions for example. i.e. I could not represent 1.75 as 1+3/4 on the Y axis with that format.

If I'm right, microsoft is using Dundas charts. So, you have a good chance of finding the related content from their forums or blogs.HTH

That still doesn't allow me to apply a custom format that I created. So, for example, if I had the values 1 through 9 on the Y Axis and instead I wanted the word in a specific language instead of the number: "uno", "dos", "tres"... etc. I would expect that the object would have allow me to attach a delegate or specify a callback function that I would write that would allow me to do the formatting and pass back the string.

I have also discovered the ChartArea.AxisY.CustomLabels collection but this is readonly so I'm not sure how it should be used. Investigating this now...

Answer 2

+1 A:

I found the answer, there's a Customize delegate that can be setup which is called after all data members have been calculated and before the chart is rendered. If you attach your delegate to the Chart's Customize event you'll be able to do all the customization you want in there.

this.Chart1.Customize +=new EventHandler(this.Chart1_Customize);
