Blank white space at bottom when plotting big data

When I plot big data with respect to time few data in plot showing white blank backgroud...i.e not starting that point spike from zero. how to resolve it. Attached matlab plot portion showing this. Thanks

The sample plot isn't attached...

A sample code/dataset that produces the symptom would help; we can't really do anything with just an image, anyway, other than look at it.

Is "big data" "big" in the sense of a large array or large range of data values to try to plot, ...???

Its is large array. Attaching with this zip file inlcudes code, data and highlighted error image for your reference. Please let me know your view. Thanks

@jalpa shah: I do not understand, what you consider as "error".

[jalpa shah]

Dear sir,

i have circled error in image file showing blank white space is coming in plot at bottom. which should start from the base of x axis. Thanks

A mark in a screenshot is not an exhaustive explanation of what the error is. Maybe the diagram is perfect and only your expectations are wrong. The code draws the diagram. Which line of code is responsible for the part you want to change?
