I am not sure what you are trying to do, however if you have x and y data in pairs as it seems you do then you can just put them directly into an XY graph as shown.

Why do you want to do it in a chart?  What is wrong with an XY graph?

 

You cannot do it in a chart.  A chart takes data, maintains a history of it, and has an initial timestamp and a delta time.  There is no way to make it display backwards.

But I saw that happens. somebody did who worked before me at my company. But I couldnt understand how did he do it.. 

I couldnt save all the data to show it on graph. I have to send just the current data because my buffer is important 😕

Hi,

 

I am still un sure of what you are trying to do.  However if it is to make the graph appear to be going the other direction then you have to manage the data you give the idicator not try to manipulate the x data etc.

 

I have attached a dirty example of illustrating data in this way.

HEre is an analiz.vi. I think you could understand my problem right now. There is two graph. When I sort The X-Channel's values decreasing, I couldnt get anysignal on the graph but when I sort The X-Channel's values increasing I could see the signal on graph.

You are not using a graph.  You are using a chart, and as I said earlier, you can't use a chart for this.  You need to use an XY graph.
