waveform chart help

[shjukheter]

Hi,

      I have taken waveform chart to display my vaoltage values dynamically. I have searched forums for my operation but did not get matched one. I want to update my chart continously for half minute and x-axis should display the current time. I have taken absolute time option in properties but it not showing the current time on X-axis(it is starting from 01:00:00). More, when i read the value now, it is ploting that value into graph and stopped there for next value(means i want to plot it same value overtime until its get new value). Is it right with waveform chart or it would be good if take waveform graph. Please suggest me.

     one more problem with my event structure that i have taken both timeout(half minute) and value updating cases in one case. So, for every half minute the values will update with out any button press but the problem is value updating is depend on other event case in my program. At starting of the program that case should run first than value updating and timeout case. ID user does not do anything except just clicked run button then problem will come that  value updating and timeout case will run first. How i handle this at the starting of the program. I hope you understand my problem.

One more problem i encountered today that is, I am displaying a user message in one event case and i am using "latch when released" mechanical action(button is placed inside the corresponding event structure). when i press the button belongs that event case, the message is displaying as well button glow short period and output from that event case is not coming. If I press again, button glows long time and result also coming regarding to that event case, if I go to other event case based on result got in previous case(that means i pressed the other button for raising other event case) then it is displaying the previous event case message(same message):smileymad: and no result in ordered one. If i press the same button againe then it is giving the needed one.

Don't understand where is the problem? can any one help me.
