Implement query builder on Statistics page. It should communicate with linear chart, that will draw out measurements based on filtering done by query builder.
There can be problem with too many points drawn on the page by the chart.
If there is a lot of entries (for example more than 500 for each series), there is applied only place or no filter. In that case we maybe should aggregate measurements by their date (without hours etc.) and show it only for the last year for example.
