Chart changes mode and causes high resource usage

I have a line chart where I load quite a lot of data. Below the chart there are some controls (range slider and numeric text box). Data loaded into the chart has no connection to the controls however the moment I change any setting using the controls the chart resets to full view (if it was zoomed), the line becomes thick and a trendline between first and last point appears. Much as the visual changes don't matter to me this chart mode causes CPU and Memory usage to sky rocket. Data I load to the chart is 500-700KB. I was looking everywhere for this setting but cannot find anything that would cause the chart to change like that. I figure this might be some touch gesture thing but cannot find any settings to turn if off. Can you help figure out why the chart behaves like that?
