Questions

I have to show multiple charts in the UI. so, I’m using a ListView and adding SciChart in the DataTemplate.
Please refer the files for more details

After the data is loaded, there is a lot of lag in zoom in, zoom out and Rubberband functionality.

Note: I’ve to load more than 4000 XY values in the series.

Could you please take a look at the same and provide some tips for improving the performance and also let me know if there is any alternative for what I’m doing?

Thanks,
Manoj

I’m pretty sure the modifier ZoomExtents fits the entire graph to the screen. But a lot of my interesting data happens right at the far right edge of my graph. So I want to add a buffer.

I’d like to zoom to XMin – XMax0.05 and XMax +XMax0.05.

I do this when loading my graph, and I’d like the double tap of my graph to also zoom to that range.

Any ideas?

Hi,

Are there any events on the chart which fires on zoom starts and zoom ends which i can use to calculate the time taken for the zoom operation.

Thanks,

Hi I am using scichartsurface with multiple y axes and a single x axis. I would want the zooming to work in a block basis as shown in the attachments.
For ex: In the first attachment I am selecting the block from 08:00:00(xaxis) and 0.76(y axis), and moving on upto 09:30:00(approx) and -22(approx). So when i start zooming the area, is it possible that it selects the entire block(A block would be distance from one major grid line to the next immediate major grid line across X axis). Please refer to 2nd attachment if unclear.

Does SciChart provide any such feature?

i have a problem with zoom : i can’t declare my function for charting inside the constructor of my class no also in the function loaded for the simple reason because i must pass two list for this function “public void CreateDataSetAndSeries(List lstX, List lstY)”, so, i create my function like this in my .XAM.cs class :

public void CreateDataSetAndSeries(List lstX, List lstY)
{
series0 = new XyDataSeries<DateTime, double>();

        using (this.sciChartSurface.SuspendUpdates())
        {

               series0.Append(lstX, lstY);

        }           
        lineSeries.DataSeries = series0;
        sciChartSurface.ZoomExtentsY();
   }

and for my class.xaml i write this :
<SciChart:SciChartSurface.ChartModifier>

<SciChart:RubberBandXyZoomModifier/>

                <SciChart:ZoomPanModifier ExecuteOn="MouseRightButton"/>
                    <SciChart:ZoomExtentsModifier ExecuteOn="MouseDoubleClick"/>

                <SciChart:CursorModifier ReceiveHandledEvents="True" ShowAxisLabels="True"  ShowTooltip="True" ShowTooltipOn="MouseRightButtonDown"/>

the problem i can’t did the zoom So what i can do ?
waiting for your response thank you !
