Hi
Thanks for your help

I send you the code. The last price changes every 5 seconds, but only the price changes, the time is always the same, it does not change. (see crosshair)
The file structure is as follows:
1.- Data Historic Data ( 5 Datapoints)
2.- Actual Data (update1(chart)
3.- Update data (update2(chart)
This is an example.
The problem is in update2(chart). I have used the option (chart.options.data [0] .dataPoints [length-1] .y = price;)
to place the data in the right place but it does not serve to update the value of time and I have not found the solution for it for updating date/time

Code : jsfiddle.net

thanks for your help

Thank you very much for your help. It was good for my job. I have it 99% completed. I just need the last step. I update the last point well but the crosshair does not update. I have used the length-1 option but the value of x is time and always has the value of the first point before updating. How could I update the crosshair?
I also thought about erasing the last datapoint and adding the new one, but I did not find the instructions to erase a datapoint. Can you give some solution?
Thanks for your help

Last question. is possible to draw this chart but dinamics data? Link: https://canvasjs.com/html5-javascript-line-chart/ (see picture in archive http://prntscr.com/kv9sp9 ) Similar at striplines but pointing specifically to the datapoint (max and min). I understand that if know the datapoints, i can to indicate manually
{ y: 520, indexLabel: “highest”,markerColor: “red”, markerType: “triangle” },
{ y: 410 , indexLabel: “lowest”,markerColor: “DarkSlateGrey”, markerType: “cross” },
but i can not to draw the highest and lowest point when the data are dinamics. I can to draw the stripline with max and min but only points no.
Thanks for your help.
