Is there an option to set the font size for the labels given to each series line, which show up to the right in Google Charts? In the overview example (https://developers.google.com/chart/interactive/docs/gallery/linechart) the labels I'm referring to are "Dogs" and "Cats". My chart has a lot of series, and the labels are too numerous and get cut off at the bottom of the chart. I want to make them smaller so they fit.
use the following option...
legend.textStyle.fontSize
e.g.
legend: {
textStyle: {
fontSize: 8
}
}

I have been attempting to get a google chart to show each and every specified value labeled along the vAxis.
Currently, the most I can can get it to show is a label for every other tick. It seems like there should be a way to get around this.
Here's what I'm seeing:
I have the vAxis options set like this:
vAxis: {
ticks: [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21],
direction: -1,
minValue: 0,
maxValue:20,
showTextEvery:1
}
What I need is for it to label each and every row, meaning 1,2,3,4,5, etc... instead of just 1,3,5,9....
if the values are specified in the vAxis.ticks option and still do not appear,
then you will need to either increase the height of the chart and / or chart area...
height
chartArea.height
or decrease the font size...
vAxis.textStyle.fontSize
I have to build a horizontal bar with chartjs. I already built a few of them but its a bit different. The chart has 2 labels for the yAxis ("Storm Risk", "Ice Risk") and hours for the xAxes. I have to print out for every hour one of these different options with different colors ("Low", "Medium", "Hight") as ye can see in the screenshot attached.
This kind of bar chart usually the values are represented by the length of the bar and its a bit different.
Any suggestion?.
Thanks
The chart you want to implement is a sort of a "heatmap". As of now (Sep. 2018), Heatmap charts are not supported out of the box by Chart.js. However, you can make one out of a stacked bar chart (in this case, probably stacked horizontal bar chart?): make each stack size equal to one another and each item backgroundColor depending on the actual values being represented. Once this is done, you can override ticks and tooltips using with according callbacks. Legend can be implemented by one more bar chart with sample values and colors.
More details can be found in a related GitHub issue: https://github.com/chartjs/Chart.js/issues/4627
Another alternative would be to use a BubbleChart. The strategy would be similar - you would need to make all bubbles same size, but override their colors. However, provided the look in the question, stacked horizontal bar chart will be more suitable.
Another option for those who are still looking is to use chartjs-chart-matrix https://chartjs-chart-matrix.pages.dev/usage.html plugin.

I have dynamic pie set and if there are a lot of series then pie get small.
How to set fixed pie chart radius.
A PiePlot grows to fill the space available, so you'll need to give it room to grow. Some possible approaches:
Override getPreferredSize() and use a suitable layout, as shown here among other suggestions.
Display the legend items in an adjacent component, as shown here, leaving the chart alone to fill it's container.
Reposition the legend within the chart, as shown here for the default RectangleEdge.BOTTOM.
One of my uses of Kibana is related to displaying some information in certain cases only (say when a value is unexpected and exceeds a defined range). This element is therefore either shown or hidden from the dashboard, and displaying it could be considered as displaying an alert. I would prefer if the related pie chart was filled in red, rather than the default green.
Any ideas on how to do this?
Assuming you are describing Kibana 3, if you want terms panels pie charts to use different colors, you will need to make a code change.
There is a way to have custom colors for your pie chart. In order to do that you'll need to create a "hits" panel and pick the "pie chart" as the display. The color of the pie slices will be determined by the color that you chose for the queries that they track:
Is it possible to change Google chart font size, my problem is that when i shrink width and height of whole chart, text becomes small and unreadable, any way to custom set font size?
Also is it posible to change tooltip size , described as a in the image?
in options, set legend and tooltip by
{legend:{textStyle:{fontSize:'xx', fontName:'xx'}}}
{tooltip:{textStyle:{fontSize:'xx', fontName:'xx'}}}
Check out here for more details
For Areachart:
var options = {
tooltip: {textStyle: {fontName: 'TimesNewRoman',fontSize: 12,bold: false}}
}
Thanks,

legend.textStyle and tooltip.textStyle control this as documented for scatter charts for instance here
