#43 Histogram Glitches
I tried to use Histogram to show battery cell voltages
Problem no. 1
Now there is some strange behavoiur when values >0 and and <0 have to be displayed .
The bars above 0 are displayed correctly , while those below 0 simply disappear
snapshot 1 histogram in CODESYS connected to PLC
Snapshot 2 histogrma in Browser ( Firegfox / Edge ... all the same )
Glitch no,. 2
Size of histogram differs ( see vertical lines )
the same behaviour occurs in my monitoring visu showing power consumption
Those arrays which do not change sign appear correctly / positive or negative ) , the others do not show negative values
A small amendment to my previous statement:
The abnormal behaviour is relatied to the type of variable
If INTEGERS are going to be displayed the problem occurs , with REAL display in correct
Looks like if integers are misintepreted perhaps
