Well, my understanding has increased and the question has changed.
The question is; when plotting 2 data series, how to get the graph to
scale and show the same series in the zoom area. When I have 2 data
series the graph determines the y axis gridlines based on the first
series but shows the second series in the zoom area. Hence, the
numbers for the second series y axis gridlines are not "pretty" ie.
they're forced to follow the grid selected for the first series.
Ideally, I want the graph to determine Y axis gridlines of the data
series shown in the zoom area.
Code:
var nmi_data = new google.visualization.DataTable();
var nmi_data_cols = 1;
nmi_data.addColumn('datetime', 'Date');
function nmi_data_create()
{
var recnt=0;
if (nmi_metar.length>0)
{
nmi_data_cols++
nmi_data.addColumn('number', 'degF');
nmi_data.addRows(nmi_metar.length);
for (x in nmi_metar)
{
nmi_metar[x][0]=new Date(nmi_metar[x][0]); //turn date str
into date obj
nmi_data.setValue(recnt,0,nmi_metar[x][0]);
nmi_data.setValue(recnt,1, Math.round((nmi_metar[x][1]
*9/5)+32));
recnt++
}
}
nmi_data.addColumn('number', "$unitsgraph");
nmi_data.addRows(nmi_param.length);
for (x in nmi_param)
{
nmi_param[x][0]=new Date(nmi_param[x][0]); // turn date str into
date obj
nmi_data.setValue(recnt,0,nmi_param[x][0]);
nmi_data.setValue(recnt,2, Math.round(nmi_param[x][1]));
recnt++
}
}
Options:
var colors = ['orange','green'];
nmi_chart.draw(nmi_data,
{
'displayZoomButtons': false,
'colors': colors.slice(colors.length - nmi_data_cols),
'scaleColumns': [0,1],
'scaleType': 'allmaximized',
'displayLegendDots': true,
//'scaleColumns': [0,3],
//'scaleType': 'allfixed',
'fill': 20,
'dummy':0 // help ensure we don't have an extra comma
});
Thanks,
