changeto chart x axis unit

[Vsh]

ok. So which input control in your vi determines the X-axis values? is it predefined or dynamically variable?

[kacco]

I want to control x axis value.This value is dynamically variable and coming from encoder every 15 c.meter. X axis and Y axis must be synchronization with my datas.

Hi kacco,

"my datas coming from fpga every 15 centimeter."

So you get one value every 15cm? If so simply change the x-scale multiplier to 0.15 and use "distance [m]" as axis label.

Again: you don't have a "default unit"! You have some default axis labels. This is quite different...

I dont know if i understood the exact requirement of urs, but kindly check the below attached VI

[kacco]

thank u for every one about my problem.Solved this problem.I didnt understand what is the meaning of x scale mutli(propertynode) ? And why multiply 0.15 ?

thank you for again

Hi Krunal,

using a waveform is ok too - with using 0.15 as dt value the requirement is fulfilled too.

Hint: save some default values in the array before posting as an example vi...

Hi kacco,

have you read the context help?

You can customize each axis to your coordinate system by using an offset and a multiplier (shift and distort).

The 0.15 should be obvious here: your data are spaced with 15cm - which is 0.15m and I suggested a label of "[m]"...

Hi ,

I get a continous streaming data from cRIO  module ethernet port.

The variables coming from cRIO are shared variable. 

My variables are:

no of pulses (distance in mm) determined from an encoder - for x axis

a sensor output during each  - for y axis

PS: Please notice encoder speed may vary - so the no of pulses per time interval which means distance data is asynchronous.

I want to show sensor output data with respect to distance in mm. 

ie:

x axis - encoder counter in mm:   0 2 5 7 8 15 ...etc

y axis - sensor output:                 5 6 6 5 4 3   ... etc

I will appretiate if anyone could help me to display the data in real time on a chart or graph

Kind Regards

Hi kacco,

use an XY-graph...

Before you always said your data is evenly spaced - atleast that was my impression!

hi,

ı use to xy graph but xy graph doesnt work with my codes.I dindt show my plots with xy graph you can send a simple xy graph  example with while loop searched and tried all labview example.
