Hello SciChart Team,

We are using SciChart v6.1.1.13156 since about a year in our main software that is used by customers worldwide.
The SciChartSurface-Style that all charts use is configured to use the VisualXcceleratorEngine (in DirectX9 mode, as some customers had problems with invisible charts on specific older intel graphics chipsets).

In the last weeks we had several inqiuiries from customers (from Japan, Korea), that the charts in their software do not update when adding new values, the chart is only updated when minimizing and then showing the window again. Another issue was that the X-Axis was updated fluently but the chart (line-chart) only very irregularly (about 2-3 times in a 30sec measurement which provides a value every 20msec). All of these customers use new laptops with 11th generation Intel CPUs. One of these had an Nvidia-graphics card installed an when forcing to use it with our software the charts worked perfectly.

We added an option in our software to Enable Software Rendering (Highspeed Renderer) to increase compatibility when having the above mentioned issues as we thought that it has to do with the VisualXcceleratorEngine, but this did not change anything unfortunately.

We want (and have) to solve this problem as this breaks the functionality of our software with some of our biggest customers.

Best regards,
Oliver from Cologne Germany

Hi, i am trying to read an excel file which contains a few column of data to be plotted. The number of series depends on number of column in the excel file. Hence, the number of series need to be plotted dynamically. Besides, for each series, the data in not plotted in one shot. There is a timer used to plot each data point dynamically.

I am trying to use “ObservableCollection” in this case, i able to create the fastlinerenderableseries and XyDataSeries for each line series and add them into the ObservableCollection. However, i do not know how to have the real time update on each line series.

Please provide me some guide or tutorials.
Looking forward for your reply.
