Think of the color palette as the starting point for your coloring scheme, and from there you can add and remove colors from the lookup table at will. For this reason, we don't keep the value you choose for color palette in the drop-down box, because as soon as you adjust the lookup table, that palette name would no longer match the lookup table you're using. Since the default color palette is "Cool to Warm", you don't notice any change when you choose that one again. And since your data arrays have a numeric range of 0, you should just see blue. If you change the color palette to "Red to Blue Rainbow", in your case, you will see the data become all red, though the color palette drop-down will not change.</div><div> </div><blockquote class="yiv6240259522gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex;"><div><div style="color:rgb(0,0,0);font-family:HelveticaNeue,;font-size:16px;background-color:rgb(255,255,255);"><div><div><div dir="ltr" style="color:rgb(0,0,0);background-color:rgb(255,255,255);"><div dir="ltr"><span style="font-size:13px;"></span></div><div dir="ltr"><span style="font-size:13px;">Also there is always latency between user inputs and </span><span style="color:rgb(34,34,34);font-family:arial, sans-serif;font-size:12.8px;">visualization.
