How to highlight the horizontal base line (y=0) for a performance chart

[Rodolphe Billottet]

Hi,

My application display real time performance chart.

Values upper the "y=0" line have outperformed, and of course underperformed  under the "y=0"  line.

So it is important to identify easily the base horizontal line (y=0).

As I have real time data, I need to have a dynamic range which increase all along the day to display all the data.

 

How can I highlight the y=0 line.  Ideal with a different color (lighter as my chart is dark)  or with a thicker line, but only that line. I want to keep the other line as it is.

I have attache a sample with an image of what I want.

 

Best regards,

Rodolphe

Hi Rodolphe,

Thanks for using Syncfusion products.

We can achieve your requirement by setting StripLine as per the below code snippet.

Code Snippet [XAML]:

<syncfusion:ChartAxis.StripLines>

<syncfusion:ChartStripLine x:Name="strip1" Interior="DarkGray" Offset="60"  Width="1"/>

</syncfusion:ChartAxis.StripLines>

 

We have prepared a sample based on this and you can find the sample under the following location:

Please let us know if you have any queries.

Hi Muneesh, happy new year

 

Thanks for your reply.

Having a constant Offset does not work in my case as my chart is real time and with an AutoSetRange.

But I have made it dynamic using RangeChanged event like below and it seems to work well.

 

void SecondaryAxis_RangeChanged(object sender, ChartAxisRangeArgs e)
{
            strip1.Offset = -e.NewValue.Start;           
}
