I am currently working on setting the Y Axis label on various charts and i was wondering if the visifire charts have this capability. I noticed that the Y Value for a given data point is a double so there is not way to set this Value as text. I have also noticed the vfChart.AxisY.AxisLabels has not ability to set text for these labels. Am i missing something?? I have attached a sample from an existing application where we did not use visifire and was wanting to get the same functionality.

Thanks

Hi Jason,

You cannot set text(string) inside AxisYLabels as Visifire doesn't support this feature. Also, we did not find the sample attached along with your post. Would you please attach the sample so that we can look into the matter again.

Here is the attachment please let me know if you know any work around or when this feature will be available.

Hi Jason,

Currently there is no workaround to achieve this as Visifire supports only double values in AxisY. It is present in our wishlist.

Hi Jason,

CustomAxisLabels for axis has been implemented in Visifire. Please checkout the blog post here. Below is an example for you.



Chart XAML

dear sir:

I am doing something similor to the abover sample but implemented in C# code.

VisifireChart Chart_Result = new VisifireChart();
List<string> YaxisLableS = new List<string>();
...
Visifire.Charts.Axis Yaxis = new Visifire.Charts.Axis();
CustomAxisLabelsCollection calc = new CustomAxisLabelsCollection();
CustomAxisLabels cals = new CustomAxisLabels();
for (int i = 0; i < YaxisLableS.Count; i++)
{
CustomAxisLabel cal = new CustomAxisLabel();
cal.From = cal.To = i;
cal.Text = YaxisLableS[i];
cals.Labels.Add(cal);
}
calc.Add(cals);
Yaxis.CustomAxisLabels = calc; cals;

Chart_Result.AxesY.Add(Yaxis);

It does not work.
Would you please give me some hits?
thank you !

I have known and corrected it.

[TripsSAR]

CustomAxisLabels cals = new CustomAxisLabels();
for (int i = 0; i < YaxisLableS.Count; i++)
{
CustomAxisLabel cal = new CustomAxisLabel();
cal.From = cal.To = i;
cal.Text = YaxisLableS[i];
cals.Labels.Add(cal);
}
calc.Add(cals);
Yaxis.CustomAxisLabels = calc; cals;

Chart_Result.AxesY.Add(Yaxis);

[s]It does not work.

I have known and corrected it.

In case anyone else stumbles across this... the fix is to .Add the new cal to the existing Yaxis.CustomAxisLabels (maybe .Clear it first), not to assign a brand-new CustomAxisLabels instance to Yaxis.
