but when i execute the code, i do not see the graph, i tried different things like
graph1.refresh(), graph1.update() and so on, but i don’t see nothing, only the axes, not the data.
Can we draw different lines in the graph with different colors?
can i have some info or a working example?
Any help?
when is there help available for all the new controls available from RAB 5.11?
P.S. maybe this is offtopic, but on one real controller i cannot use hyperterminal to debug memory management, i connect it to the console port, i can see the messages when booting and everything, but when i press “enter”, i don’t get the “->” arrow so i cannot type any commands. any idea? hardware failure?
on another controller it works fine, so it is not my cable or computer.
Is there a possibility to read the available memory of the FP and write it to a RAB screen?
the code works, i use RAB 5.12 on robotware 5.11.02.
I forgot the define the plotstyle.
I have a question about the graph control
If i use:
graph1.XAxis.minvalue=10;
graph1.XAxis.maxvalue=0;
the plot is still plotted in X from 0 to 10.
so is there another way to plot Xdata from 10 to 0 for example
I want to do this, because i want to plot measuredata in function of a robotposition in search, but sometimes the movement is in +X and sometimes the movement is in -X, but i want to plot the measures from start to finish.
For the moment i make the Xmeasures negative in case of -X searching so my plot plots well,
but now i see negative X numbers on the plot, but if it is not possible another way i can live with that.
i am reading a log file created in rapid by the robot on a background task that is recording the current robot position and an analogue input while moving the robot.
the data in the logfile is for example:
1/50/300
2/55/250
3/60/210
4/65/400
where the first data is datacounter, the second the robot X position, the third an analogue input from height sensor
but when i am searching in the other direction my logfile is
1/65/300
2/60/250
3/55/210
4/50/400
for the graph control i now read this logfile line by line, use the second data as Xvalues and the third data as Y-values.
i did it before with drawline,drawellipse, drawstring and calculate the coord of drawing on the screen including scaling and labels on the axis, but is was alot of work.
i created a 4th data with the position starting from 0, used this data as Xaxis to draw the lines on the screen and use the second data to show the labels ( for example Xmin=65 and Xmax=50.
with the graph control it would be a lot easier and a little fancier.
another question:
when i used drawline, drawellipse and so on, when i leave my RAB window (for example to view “production window”) and then go back to RAB window, my drawings are gone, i use the form.onpaint method to redraw them, is that normal behaviour and the right way to do it?
