Issue with chart label formatting

[Kieran Pierce]

Hi,

I have this code set in my XAML

<chart:SfChart.SecondaryAxis>

            <chart:NumericalAxis>

              <chart:NumericalAxis.Title>

                <chart:ChartAxisTitle Text="{Binding Detail.Result.Result.AxisCostLabel}"/>

              </chart:NumericalAxis.Title>

              <chart:NumericalAxis.LabelStyle>

                <chart:ChartAxisLabelStyle LabelFormat = "0:0,0"/>

              </chart:NumericalAxis.LabelStyle>

              

              

            </chart:NumericalAxis>

          </chart:SfChart.SecondaryAxis>

but it has no effect, i am expecting the chart labels on the axis sot be formatted with no decimals and a , as thousands seperator

Hi Kieran,

Thanks for contacting Syncfusion support.

It is possible to achieve the specified requirement by setting the LabelFormat as shown below.

<chart:NumericalAxis.LabelStyle>

  <chart:ChartAxisLabelStyle LabelFormat="#,###.00" />
</chart:NumericalAxis.LabelStyle>

That works, I have moved the format into a binable paramater and this is also working fne, but it will not work on the label formatiing of the trackbacll

I have this 

<chart:ChartTrackballBehavior.LabelStyle>

                <chart:ChartTrackballLabelStyle LabelFormat = "{Binding Detail.Result.Result.CostFormat}"/>

              </chart:ChartTrackballBehavior.LabelStyle>

and this

<chart:NumericalAxis.LabelStyle>

                <chart:ChartAxisLabelStyle LabelFormat = "{Binding Detail.Result.Result.CostFormat}"/>

              </chart:NumericalAxis.LabelStyle>

the format on the axis is fine, but not on the track ball, I can set the label format manualy on the track ball which does work but i want to bind it in order to set pre and post fixes based on data in the model

any ideas?

so i took a look at the sample, it did not work. i updated my version of sfchat to the one i can download to day. Now in debug i see the binding collect the formtatting but track ball does not work at all in IOS simulatre in my project or in the what could be happing?

[Kieran Pierce]

That message was not great I typed it on my phone.

What I am trying to say is:

On my system the Sample and My App does not work. With an older version of the .dll the trackball works on the graph but with the issue I have been having on the data binding. I have upgraded the .dll to the latest version I downloaded form the site today. This has made the data binding work. But the trackball is not working at all on the simulator and a real phone all running IOS 9.2, what I mean buy his is that dragging my finger over the graph I see no trackball info any more.

[Kieran Pierce]

I just tested this on Android and here the Trackball does work but the formatting of the label will not databind. can you confirm the version of the dll files you are using please

Hi,

I can now get the sample to work, the odd thing is that none of the chat behaviors work in my app, they used to

I have finally tracked down the issue. you need to have 2 charts on the same page, then the chart behaviours only apply the last one added. how to fix this?

[Saravana Pandian Murugan]

Hi Kieran,

We are unable to reproduce the reported issue. We have prepared a sample which contains two Charts on the same page. Please download the sample from the location given below.

[Kieran Pierce]

The issue is if you set the second chart in the stack to invisible
