Most ChartFactory methods include a boolean tooltips parameter. Just look in the source for your factory of choice to see how to instantiate a default tooltip generator suitable for the designated renderer. You shouldn’t need to handle the events yourself. Addendum: As you are using createXYLineChart, an instance of StandardXYToolTipGenerator is supplied by default. The … Read more
It would probably make sense to let annotation_custom access facetting info *; this trivial change seems to do the trick, library(ggplot2) library(grid) library(gridExtra) annotation_custom2 <- function (grob, xmin = -Inf, xmax = Inf, ymin = -Inf, ymax = Inf, data) { layer(data = data, stat = StatIdentity, position = PositionIdentity, geom = ggplot2:::GeomCustomAnn, inherit.aes = … Read more
Here you can find my solution – MultipleAxesLineChart. It is not generic and just fits my needs, but I think it can give a good sight of how it can be done by using StackPane.
You’ll have to loop through the data and get the total, and then use the datalabel formatter function to get the percent. Example here: http://jsfiddle.net/JVNjs/319/ formatter:function() { var pcnt = (this.y / dataSum) * 100; return Highcharts.numberFormat(pcnt) + ‘%’; } edit:: updated example with axis labels: http://jsfiddle.net/JVNjs/320/ [[EDIT for comments If you are trying to … Read more
Here’s what did it for me- after I created the chart I added the following lines: chrtMain.Series[0].YAxisType = AxisType.Primary; chrtMain.Series[1].YAxisType = AxisType.Secondary; chrtMain.ChartAreas[0].AxisY2.LineColor = Color.Transparent; chrtMain.ChartAreas[0].AxisY2.MajorGrid.Enabled = false; chrtMain.ChartAreas[0].AxisY2.Enabled = AxisEnabled.True; chrtMain.ChartAreas[0].AxisY2.IsStartedFromZero = chrtMain.ChartAreas[0].AxisY.IsStartedFromZero; There was no need to superimpose two charts or anything!
UPDATE chart.js 2.1 and above var chart = new Chart(ctx, { … options:{ scales:{ xAxes: [{ display: false //this will remove all the x-axis grid lines }] } } }); var chart = new Chart(ctx, { … options: { scales: { xAxes: [{ ticks: { display: false //this will remove only the label } }] … Read more
In Chart.js version 2.0 this is possible: options = { scales: { yAxes: [{ scaleLabel: { display: true, labelString: ‘probability’ } }] } } See axes labelling documentation for more details.
Try adding the options.scales.xAxes.ticks.maxTicksLimit option: xAxes: [{ type: ‘time’, ticks: { autoSkip: true, maxTicksLimit: 20 } }]
I am the author of “Algorithm for Optimal Scaling on a Chart Axis“. It used to be hosted on trollop.org, but I have recently moved domains/blogging engines. Anyhow, I’ll post the contents here for easier access. I’ve been working on an Android charting application for an assignment and ran into a bit of an issue … Read more
ggplot(df, aes(x = factor(Time), y = Value, fill = factor(Type))) + geom_bar(stat=”identity”, position = “stack”) ggplot(df, aes(x = factor(Time), y = Value, fill = factor(Type))) + geom_bar(stat=”identity”, position = “dodge”) You can do one or the other but not both. When they are dodged, the different values of type are being used. By adding a … Read more
