问题 I have a line chart. Its purpose is to show the amount of transactions per user over a given time period. To do this I'm getting the dates of all users transactions. I'm working off this example : http://bl.ocks.org/mbostock/3884955 and have the line chart renedering fine. My x-axis is time and the y-axis is number of transactions. The problem I have is to do with displaying dates when there is no activity. Say I have 4 transactions on Tuesday and 5 transactions on Thursday..I need to show

How to set tooltips to display percentages to match axis in Google Visualization Line Chart?

孤人 提交于 2019-11-30 11:18:51
The tooltips can be set to display percentages using the following code: var formatter = new google.visualization.NumberFormat({ fractionDigits: 2, suffix: '%' }); formatter.format(data, 1); // Apply formatter to first column. Is there a way for NumberFormat to multiply each element by 100? Otherwise the tooltip appears as .50%. I am using vAxis.format = "format:'#%' " which does multiply by 100. So .5 is displayed as 50% on the vertical axis. According to the documentation( icu-project.org/apiref ), this can be overwritten by enclosing the % in single quotes, but this did not work. The net

The legend for d2 looks fine; for d1 , I would like to show just the hoizontal line against a white/transparent backgounnd. df = data.frame( Date = c("2012-11-30", "2012-12-03", "2012-12-04"), d1 = c(9, 5, 11), d2 = c(4, 6, 3) ) ggplot(df, aes(Date)) + geom_bar(aes(y = d2, color = "d2"), stat="identity", fill = "red") + geom_line(aes(y = d1, group = 1, color = "d1")) + scale_colour_manual("", values=c("d1" = "blue", "d2" = "red")) It is not an elegant solution but at least it gives some result. I added aes(fill="d2") in geom_bar() and removed fill="red" . Then I added separate scales for line

Points on a line in jfreechart

我的未来我决定 提交于 2019-11-29 15:52:54
How to get all the points (x,y) lying on the line connecting two data-points in a chart in jfreechart ?. In a chart, as we point to the end-points of the line, it shows the x & y coordinates. Can't we get the coordinates at any point on the line (via code)? As you have two points, use the formulae of a linear equation to obtain the slope and intercept of the line. Once you have the equation, you can evaluate it at any point. Addendum: The org.jfree.data.statistics.Regression class offers some built-in support for regression analysis. 来源: https://stackoverflow.com/questions/10086306/points-on-a

MPAndroidChart How to represent multiple dataset object with different number of points in the same chart line

隐身守侯 提交于 2019-11-29 12:12:09
I am using MPAndroidChart for charting. I am building a line chart which has multiple dataset objects. From the examples provided by MPAndroidChart I can observe that multiple dataset objects can be drawn in the same line chart but with the same number of points (y-values) and those y-values referenced to the same x-values. What happens if I want to draw multiple dataset objects in the same line chart with different number of points (y-values) referenced to different x-values for each one? How can I get rid of this? I cannot be able to do it. For example: Dataset object 1 Y-values: 0, 12, 23,

Two chart types (bar and line) in same SSRS chart

吃可爱长大的小学妹 提交于 2019-11-29 03:13:57
How can SSRS 2005 represent two chart types (i.e., bar and line) on the same chart? I am trying to create a graph that looks like the professionally crafted image below: The chart would have one series represented as bar graphs and then two other series represented as overlapping line graphs. I have the line graphs working as two independent series and I can write my SQL query to return empty values for the months of the bar graph series and empty values for the years on the two line series to prevent overlapping, but I don't see how to specify a chart type per series. Realistically, can this
