I'm migrating some old PHP web pages to Perspective. The original is generated using jqPlot which has the nice feature of being able to add in in the batch sequence numbers shown in green circles on the chart below. The batch sequence number is repeated in a table below the chart. This makes it easy to find the batch's corresponding row in the table.
Can anyone think of a way of achieving a similar result in Perspective's XY Chart?
I can generate datapoints with X value to match the end of weighout and a constant Y-value of 70 kg.
How could I generate the labels?
How could I embed the 1, 2, 3, ... batch numbers?
Many thanks.
It seems that my best shot is,
- Create a batch-number dataset with (t_stamp, number) pairs. Number is in sequence 1, 2, 3, etc.
- Create another y-axis. I set the axis range to very large numbers so that the difference in vertical position of my batch numbers is not discernable. In my case I made it
max : 1000 and min : -10000. This forces the zero line above the top of my other charts.
- Add another series and set it to line. Bind it to the batch-number dataset.
It's not exactly what you're asking, but you could use tooltips and bullets on the weight dataset and put the batch number in that datasource.
I don't think one can do that. The tooltips can read {valueY} but not other columns in the dataset. I've posted some work on the XY Chart tooltips here. In any case they don't appear until the user hovers over the point so - no use!
I've added tooltips to the batch number bullets so now I have both.
Now to try and add a circular backfill ...
