问题 from hours I've been looking for a solution to add trendlines to an existing chart built with Chart.js I think we can only add logarithmic trendline on Chart.js ? I don't want to draw a trendline from scratch, but add 2 trendlines based on existing data of these 2 lines ; please see this fiddle example : THANK YOU https://jsfiddle.net/blueagency/p88mx3nw/ A big thank you in advance for all your help. 回答1: Currently, chart.js does not have a trendline capability at all (not even logarithmic).

问题 I'd like to create a broken vertical bar graph in matplotlib. To give a better idea of the result I'm after, I put an example together with Balsamiq: I've had a look at the matpltolib docs and examples but I can't seem to find the appropriate chart type to use. The only thing that looks remotely similar is the boxplot but this isn't what I need. I'd rather not have to draw the graph manually with graphics primitive. I can massage the data into shape as needed. PS: If you know of a good

问题 Using Chart.js you can create line charts and for that you have to privde labels and datasets. for example: var data = { labels: ["January", "February", "March", "April", "May", "June", "July"], datasets: [ { label: "My First dataset", fill: false, lineTension: 0.1, backgroundColor: "rgba(75,192,192,0.4)", borderColor: "rgba(75,192,192,1)", borderCapStyle: 'butt', borderDash: [], borderDashOffset: 0.0, borderJoinStyle: 'miter', pointBorderColor: "rgba(75,192,192,1)", pointBackgroundColor: "

问题 can any one show me I might be able to use custom colours in an ASP.Net chart control. so for example I have two series TOTAL and TARGET and I want to set the colour for total to green and the colour for target to be red . 回答1: Something like this: Color[] colors = new Color[] { Color.Green, Color.Red }; foreach (Series series in Chart1.Series) { foreach (DataPoint point in series.Points) { point.LabelBackColor = colors[series.Points.IndexOf(point)]; } } 回答2: iv done something like Chart2

问题 I want to display some Data with googles Scatter Chart. No matter how I try I can't get the y axis labels to show. I tried various things, which were suggested here and on other forums. Including: Resizing the chart, resizing the label font, Rescaling the axis and changing the textPosition of the vAxis. None of this worked. The funny thing is that the ticks I defined are showing correctly placed gridlines. It is just the labels that are missing. The axis title is also displayed which leads me

问题 I'm styling some chartjs bar charts which need rounded corners at the bar's values (not their base), In most cases this means rounded corners at the top of the bar's however there are also instances where the bars have negative values. I've used the answer here: How to create rounded bars for Bar Chart.js v2? provided by jordanwillis (https://stackoverflow.com/users/7581592/jordanwillis) which works great when values are positive but not when values are negative. See attached example: bars
