Hello, i am trying out the graph control. i use Double PX={1,2,3}; Double PY={3,2,1}; graph1.addpoint(PX,PY); 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? Kind Regards Peter ---

Hi Peter … I have not tried this code in the RAB 5.12. Could you verify it works? Thanks [webwiz/2219/TpsFormGraphStatic.zip](http://forums.robotstudio.com/webwiz/2219/TpsFormGraphStatic.zip) ---

Hi carlos, 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. Kind regards Peter ---

Hi Peter, Can you send me the RAPID modules or data you are planning to graph? I can’t promise anything, but we can see if there is a workaround … BR ---

Hi carlos, 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? ---

Hi Peter, How is all things going on?
