Optimal settings for zoomRange and panRange - TimeStamp - two data sets

[Michał Szyper]

Hi

Im reciving data form sensors and putting them into flot chart and i have problem with zooming.

How to set correct value of zoomRange and panRange on X, Y.

Im using now that settings but is not fine for me:
               
                        var min_m = <?php echo json_encode($min); ?>;
                        var max_m = <?php echo json_encode($max); ?>;

                        xaxis: {
                                mode: 'time',
                                timeformat: "%H:%M<br />%d/%m/%y",
                                zoomRange: [0.1, 3600000000],
                                panRange: [min_m,max_m]
                        },
                        yaxis: {
                                zoomRange: [0.1, 20],
                                panRange: [-30, 100]
                        },

Values I get are: temperature (from 2 sensors) and timestamp
