I've had some initial investigation and you might not need a specific historic chart component. See the attached using existing charts. The html is in the zip file. The slider sets the rate (1ms to 1s) and the combo is the width of the data shown. I've quickly thrown it together and it's a bit buggy...

External code can be included in Supplementary Code. See: https://www.flowcode.co.uk/wiki/index.php?title=Supplementary_Code Instead of adding the code directly to Flowcode, add statements into Supplementary Code such as the following to point it at external files: #include "C:\MyFolder\MyCode....

My thinking is it's the speed of receiving the data that is the bottleneck rather than the speed of the device hosting the app. What are your requirements for a scrolling chart in terms of throughput (number of datapoints per second and number of datapoints on the chart as a whole)? That might help ...

That's great, Martin. Thanks for reporting back. It looks like maybe the "Makefile.txt" (etc) files are not actually in that "...ESP/Batch" folder. These should have been downloaded when you did a full library update. I'm not sure why they should be missing. Anyway, at least Ben'...

Thanks, Iain. Looking on the web, there are a number of possible causes/solutions such as: Need to right-click a subprocess System configuration has "write debugging information" set to 'none' System files are corrupt (need to run sfc and/or dism to fix) 3rd party tool to blocking dump cre...

One way to solve this is to have a timer interrupt constantly running which simply increments a global "tick" integer variable. In your main macro, have something like: //initialise some vars Set tick to zero Set check1 to false Set delay1 to an appropriate value ...etc... Enable Timer Int...

Web Developer projects are very different to PC Developer and Embedded projects in Flowcode. We are investigating a scrolling historic chart for Web Developer, but it might be too slow to be useful.

(edit: Ben beat me to it!) Those folders are populated when a compilation takes place. I've tried compiling your project and it compiles ok on my PC. Comparing the msg.txt file, yours has 4 "The system cannot find the file specified" errors near the start after the "Building: 1Hz flas...

The Test & Debug pack was a stand-alone pack in v9, but is included in the Professional pack in v10 and v11 and is no longer separately available.

Please post the fcfx and msg.txt files as that will help solve the problem.
