Line chart widget used with live data resizes unpredictably
Posted: Fri Nov 04, 2016 4:15 am
LiveCode 8.1.1 Build 14008
Using Line Graph widget to display live temperature information extracted in LC from a comma delimited .txt (log) file.
Using
to produce a JPEG which I upload to my FTP servers (still within LiveCode).
A new JPEG is uploaded every 5 minutes and displayed HERE… (see link bellow)
My problem: the chart won't keep still over time and stretches randomly horizontally,
also, the y axis fills up with redundant values and unevenly spaced numbers.
This makes for quite a spectacular show when I animate all the screen shots (snapshots) together.
See attached bellow a very short, and heavily cropped, .MP4 animation spanning 14 hours of data acquisition.
You can clearly seen the jittery behaviour of the chart in this animation.
Of course, "Lock size and position" for this object has been checked.
Latest Data (CSV) content (copy & paste) from widget:
-24h,11,5,8,6
-22h,11,5,8,6
-20h,10,5,8,6
-18h,10,5,8,6
-16h,10,5,8,6
-14h,10,5,8,7
-12h,10,6,10,8
-10h,10,7,11,10
-8h,11,7,12,10
-6h,11,6,10,8
-4h,11,4,8,6
-2h,10,5,8,6
