how to return moving string data, line, and numeric on a waveform chart??

[alfredo_2k2]

dear all..
I have a problem to return a moving string data, line, and numeric on a waveform chart.
I tried to return a data each time i interupt by using a controll with event case and i want the current data is holding on till i release the control button, next the data will empty but actually keep moving relative to horizontal scale, and return data again when i interupt it. I want to return those three datas on a waveform chart.
I hope all of you can help me to fix my problem.
 
thanks in advance..

The description of your problem is a little confusing.

couold you attach the code of what you are trying to achieve?? it would help us answer better

It looks like a LabVIEW related query.

I would advise that, in future, post such queries on LabVIEW discussions board for a quicker reply

okay.. i hope this will explain better.

i have a waveform chart returns plot of datas from my acquisition card.

aside from plotting those datas, i need that chart also plot other datas like string data, and numeric data.

can u help me to do that??

i think it isn't something to show in a code coz my code is actually can be subtituted with a plot of a sinus on a waveform chart.

the problem is, can i plot other types of data like numeric or string on a chart??

thats my question.  hope u can help me do this.

thanks.

Andre.

Yes the Numeric data can be plotted on a chart. Look at the chart example vi's, that are shipped with LabVIEW

string data?? could you please explain that a bit more?? do you mean plot a text on a chart??

dear dev.. i'm sorry if i cannot explain it clearly.

yes, i actually want to plot text on a chart, and the numeric data i said before is a number, not a point. 

please help me if u know how to do that.

thanks dev.

Well, you cannot feed strings and numbers as display parameters to  a chart

If you could explain what exactly is the type of string display that you want to do, we could suggest some tricks to make a string 'apparently/virtually' appear on your chart's plot area

dear dev,

i want to display or plot text data just like a moving letter same with the moving point from signal generated by DAQ.

but it is not continuous. for example: if i push a button that equivalent with "A" then "AAAAAAA.........." will be displayed on the chart till i release the button. And sometimes, there will be three text datas are stacked, displayed simultanously. I still not found how to do this...

if u can get me a trick, i would appreciate it.

regards.
