Basically I want to hide dash between the bars from waterfall chart.I am using highcharts iOS wrapper.I can only change type of dash but there is no option to hide or disable the same
You need to set lineWidth property to 0:
let plotOptions = HIPlotOptions()
plotOptions.waterfall = HIWaterfall()
plotOptions.waterfall.lineWidth = 0
options.plotOptions = plotOptions

I have a stacked bar chart that only ever has 5 categories(but the value of the categories change from year to year, it is a sliding 5 year window).
I have successful customised the bars to the colors I want.
But now I wish to make the label of each Category the same color as the customised bar color.
Is there a way to do this?
You can use custom code for this.
In Report Properties | Code, you can paste in the following code:
Private colourPalette As String() = {"#418CF0", "#FCB441", "#DF3A02", "#056492", "#BFBFBF", "#1A3B69", "#FFE382", "#129CDD", "#CA6B4B", "#005CDB", "#F3D288", "#506381", "#F1B9A8", "#E0830A", "#7893BE"}
Private count As Integer = 0
Private mapping As New System.Collections.Hashtable()
Public Function GetColour(ByVal groupingValue As String) As String
If mapping.ContainsKey(groupingValue) Then
Return mapping(groupingValue)
End If
Dim c As String = colourPalette(count Mod colourPalette.Length)
count = count + 1
mapping.Add(groupingValue, c)
Return c
End Function
This will give you the option of the pastel colour palette. If you want other colours, simply replace the hex colour codes with values of your choice.
To use this, simply use the following expression:
=Code.GetColour(Fields!Thingy.Value)
Use this on your series and your label fill expressions. This will ensure that the same colour appears for both. If you have multiple graphs with the same values in, this will also ensure that the same data series across multiple graphs always have the same colour.
I am using iOS Charts with Swift 3, and I can't figure out how to do a couple things:
I want to remove the margin around the chart. I know the chart goes edge-to-edge in my UI because if I change the chart's background color, it goes all the way to the edge. How do I remove the gap indicated by the red arrows below?
How do I remove the border around the whole graph (note the black arrow)? I already have totalsGraph.drawBordersEnabled = false and it doesn't work. Is there a different option for that?
Thank you!
It is minOffset.
/**
Sets the minimum offset (padding) around the chart, defaults to 10
*/
You can change it as this:
chartView.minOffset = 0
that line is actually axis line.
To hide the all the lines, you can use
totalsGraph.rightAxis.enabled = false
totalsGraph.legend.enabled = false
totalsGraph.leftAxis.enabled = false
totalsGraph.xAxis.labelPosition = .bottom
totalsGraph.xAxis.drawGridLinesEnabled = false
totalsGraph.xAxis.drawAxisLineEnabled = false
I am looking for solution to remove margins as well. I will update my answer when I find it.
Actually the way to do it is like this:
chartView.xAxis.enabled = false
chartView.leftAxis.enabled = false
chartView.rightAxis.enabled = false
chartView.drawBordersEnabled = false
chartView.minOffset = 0
I'm using ios-charts (https://github.com/danielgindi/Charts). I have a LineChartView with 12 values in the x axis.
This however is far too many to see at the same time, so I want to display only 5 and then let the user drag to the right to see the next.
I've tried this:
let chart = LineChartView()
chart.dragEnabled = true
chart.setVisibleXRangeMaximum(5)
let xAxis = chart.xAxis
xAxis.axisMinValue = 0
xAxis.axisMaxValue = 5.0
xAxis.setLabelsToSkip(0)
But still see all 11 values at the time. How can I only see 5?
I finally got it!
The correct answer is:
chart.setVisibleXRangeMaximum(5)
This however needs to be set after the data has been set in the chart (not in a configure before)
This did the trick for me
You should set the X axis's labelCount property of the chart view.
In objc,like this
_chartView.xAxis.labelCount = 5;
Swift
chartView.xAxis.labelCount = 5
Here is my finding!!
you don't need to really use label count
if you are using DefaultAxisValueFormatter, NEVER use this. a lot of errors pop ! just use no2.
chart.setVisibleXRangeMaximum(number) will do.
please put this after chart data setting here you can see detail
combinedChartView.data = combineData. //this need to come first
combinedChartView.setVisibleXRangeMaximum(2) //after data setting
I need disable some elements from my chart.
I used the iOS-charts library in (Swift 2), however I can't understand how to disable the following:
Hide right and left numbers
Hide description color square
Hide all vertical lines
self.chartView.xAxis.drawGridLinesEnabled = false
self.chartView.leftAxis.drawLabelsEnabled = false
self.chartView.legend.enabled = false
will do the job
self.chartView.drawEntryLabelsEnabled = false
This will hide the label from PieChart and shows only value. Also shows legend with label texts.
For only hide the top one:
graphCell.lineChartView.leftAxis.drawTopYLabelEntryEnabled = false
I'm using Rickshaw with d3. I would like to show the x axis value when I'm hovering over a bar on the bar graph, but I would like to disable to hover effect that shows the series type and the y axis value.
Is there a way to only display one and not the other? I tried doing this and it doesn't work (i'm compiling this coffeescript to javascript):
hoverDict =
graph: graph
xFormatter: (x) ->
today = new Date()
today.setDate(today.getDate()- x + 1)
return today.toDateString()
yFormatter: null
hoverDetail = new Rickshaw.Graph.HoverDetail(hoverDict)
I figured it out. You have to edit rickshaw.css for the .item.active field:
.rickshaw_graph .detail .item.active {
opacity: 1;
display:none;
}
Making display:none will make the yFormatter not display.
