real time graph in touch panel module

Hi All, I,m trying to graph a scalar value , as random number for example, in a waveform graph with X axis in absolute time.

I did it with "built waveform" or using the block " to DDT" in express library,but no success.

I have red the help and it seems is possible to develop applications with DSC, but does it means that we can use the DSC tools to develop an application for touch panel?

I,m using Labview2010 with touch panel module

Could anyone help me ?

 

Thanks in advance

Hello Icaro600,

 

I think this link is the answer of your questions:

If not, attach a VI example of how are you trying to implement this right now.

Hello Sendia,thanks for your response. The problem is I,m using TouchPanel module to develop an aplication in ARM9 mini2440 S3C2440 board, and have limitations. See attached file.

If I put autoscale in x axis it seems ok, but if remove autoscale there is plotting nothing or the plot is irregular

 

Thanks in advance

It is nothing related with Touch Panel Module limitations but Graphs configuration. To represent absolute time you have to configure the graph scales properties with this option.

 

In the previous post you said that you are using Waveform Graphs but the example is with Waveform Charts that is something different. You want to use Graphs or Charts?

Hi Sendia, see attached a video and the configuration of the waveform chart.

I adjusted the chart bhistory length to 16 to force the chart to strip early. it seems when the buffer finish is mixing the new data with the old one.I have tested in the three differents modes of update.-

See also how the time is increase by 3 every update of the chart.

hope this helps.

 

best regards

HI, I have been tested the two examples, in the first one appears a message of "property method not supported in the current target" , this is about the history property method.

The second one do the same I showed you in the video.
