Question about Real-time Line

[hellokitty]

Hi,

 

 

 

I'm new to this. I was successfully able to recreate the data displayed over time based on randomly generating numbers over time. However, how do I create a whole line chart to draw each second with a whole set of data (for example with 100 points). For example, I would like to use the X-axis for MHz values and the Y-axis for dB values. I don't want to set the Y-axis over time but to refresh the whole chart every second or faster. Thanks in advance!

Greetings Hellokitty,

 

 

 

Yes, this is possible in FusionWidgets.

 

 

 

Say, for an example, you're working over HTTP and you need to make sure that you utilize the bandwidth very efficiently. So, you cannot really set the chart to update itself every second, as that might create a strain on your server. However, you would also not want to skip those data which you missed by not updating every second. In such cases, the multiple data update feature comes in handy. You can then provide the following data update from the server:

 

 

 

&label=11:45,11:46,11:47&value=23,25,24|43,47,45|45,47,49

 

 

 

In the above data, we're providing three updates to each of the lines present on the chart. Also, we're providing three new labels for the x-axis.

 

 

 

NOTE: To provide multiple data in a single update, you need to separate the values within the data-set using commas. Each dataset still gets separated from other data-sets using the pipe (|) character.

 

 

 

In case you're using data-sets, then you'll be happy to know that all the data-streaming charts can have any number of data-sets in them.

 

 

 

You can also use the refreshInterval attribute to set the refresh rate. It accepts increments of a number as a value(seconds) too. For example .3 and .7 etc.
