Please see the modified app attached.
In keeping with the existing design where the plot is updated when the Generate Plot button is pressed, I modified GeneratePlotButtonPushed to use the date pickers' Values and only plot data within the selected date range.

Yes i got your point . I have attached my application with excel file and a screenshot. When i select 2 march to 6 march for an eg as shown in screenshot. It is plotting a total of 55-60 data the rest data is not being plotted.Even if i select direclty without the ui date picker it is not plotting all the data. So thats my issue did u get it.????????

Thanks for the updated app and data file. I am able to reproduce your screen shot. I don't agree that it is plotting 55-60 data points. I find that all the data is being plotted. To be sure of this, I put a breakpoint in GeneratePlotButtonPushed and checked the values of start_idx and end_idx (exactly as I recommended you do in a previous comment); I found start_idx is 2 and end_idx is 123 which means 123-2+1 = 122 data points are plotted, which is everything in the file (ignoring the first row of app.t, which starts with NaT and is due to a blank row in the file immediately after the column names). What makes you say only 55-60 points are plotted?
Note that the data look like three spikes because there is only data within three relatively small time ranges: 02-Mar-2024 14:06-14:11 (~5 minutes), 05-Mar-2024 09:13-09:18 (~5 minutes), and 06-Mar-2024 17:10-17:24 (~14 minutes). When plotted against a range of several days, these brief few minutes where there is data look like narrow spikes, but if you zoom in horizontally you will see all the data is there.
