Hi! I am trying to visualize the data in a TimeChart according to a moving window. By that I mean, for example, in a chart with 1000 data points:

• On frame 1: Show data points with timestamps (x axis) from 1 to 100
• On frame 2: show datapoints with timestamp from 2 to 101
• Frame 3: 3 to 102

I have tried multiple different ways:

• Set Plot Scale by Range updated on tick (freezes the editor)
• Create a new datasource with only the visible subset of data points to be shown for that frame (it's slow, and also the chart's scale updates to include all points the chart has ever seen, so on frame 3 I see points 1 to 102)
• On every tick, remove all series from the data source and re-add the data points to be shown for that frame only (same problem as above)

Is there another way to achieve this?

Thanks in advance!

I'm cross-compiling a project with KantanCharts.

Cooking for Windows works fine, but for Linux the log says:

Any ideas how to add it?

Using UE4.25

When the current data on the Y-axis exceeds the maximum seen the limit grows which is good, fit to data.

However, when the sliding time window no longer sees this maximum the limit should shrink to the new maximum. This is what you see in real time data display in labview and many other real time applications. I expect this would be quite easy to fix.

UE4.27 (I know... stuck in the past still)

This plugin is working great in editor or via remote connection to a AR headset (Hololens). However, in a packaged build the widget using KantanCharts fails to work. Checking the log provides the following error:

Couldn't find file for package /Script/KantanChartsUMG requested by async loading code. NameToLoad: /Script/KantanChartsUMG

Anyone have insight on how to address this? I've scoured the forums with no success. There are numerous hits but the underlying issue doesn't seem to be the case. I'm guessing there is something that doesn't agree with UWP needed for Hololens builds but not sure as no other errors show up anywhere.

Also, no "Script" folder exists that I can find.

Any help would be immensely appreciated.

Hi, I'm trying to have a bar chart with a Y axis that includes negative values (e.g. max value 100, min value -100, all bars drawn from 0), is there any way to do this currently?

Restarting the editor fails to recognize everything related to Kantan in Blueprints. However, the functions do exist because I can readd them.

The error message says "Failed to load /Script/KantanChargsUMG.SimpleTimeSeriesPlot Referenced by K2Node_CallFunction_0"

The function calls in the blueprint get renamed to "BP Add Series With Id"

Let me know if I can gather any further information, great plugin for plotting!

UE4 4.23.1

Hello,

I have tried to utilize your plugin on UE5.1 but it does not work even if i try to rebuild my project. Any help?
