问题 I am using Google Chart API to create a histogram and want to modify bars to fuse with the ones next to them and change the xticks to integers. Question: How can I do the following: Fuse the bars with the one next to them? Make the h/x-ticks appear as int s? Current Output: Ideal Output: Relevant Research: I couldn't find all that much, apart from these two which helped with some of my problems but not the two above: How does one go about creating an Histogram using the google chart api?

问题 I would like to remove the gridlines of the hAxis but with keeping the ticks' little black marker. My code looks like this: var optionsSmall = { colors: ['#4572A7'], hAxis: { minorGridlines: { color: '#000' }, gridlines: { color: 'transparent' }, format:'MM/d/y', textStyle: { fontSize: 9 } }, series: { 0: { targetAxisIndex: 1, }, 1: { targetAxisIndex: 0, type: 'line' } }, vAxes: { 0: { gridlines: { count: 0 }, textStyle: { fontSize: 9 } }, 1: { gridlines: { count: 8 }, textStyle: { fontSize:

问题 The chart appears with dark background, axis numeric labels in grid positions are yellow. How do I change axis label colors to white? E.g. in this example https://www.arction.com/lightningchart-js-interactive-examples/#edit/lcjs_example_0001_simpleScatter I'm trying chart.getDefaultAxisX() .setInterval(0, 92 * dataFrequency) .setTickStyle((visibleTicks) => visibleTicks .setLabelFillStyle( color: ColorRGBA(255, 255, 255) }) ) But it's giving SyntaxError: Unexpected token, expected "," 回答1:

问题 So I've got a timeline with data in it that can be concurrent... When I move the ChartRangeSlider to a different timeframe, some of the timeline bars will either disappear or show because there is nothing happening in the timeframe that is active. These is how the timeline and the range slider are set up. I don't have any event listeners running... // Configure range slider var timelineRangeSlider = new google.visualization.ControlWrapper({ 'controlType': 'ChartRangeFilter', 'containerId':

问题 I'm trying to create some GAUGE graphs with Google Graphs. My goal is to load the data from a php page and have an auto refresh. I was able to do that, but when the data is refreshed, the Gauge lines are not animated, but instead they are redrawn from new. I would like to see the cool animation like this: https://jsfiddle.net/api/post/library/pure/. Actually I'm loading the data from a static file, then I'll create the data from a MySQL database (tested and worked). Here my code: temperature

问题 I'm using Visual Studio 2017 and am trying to make a program that shows real-time values in a scatter chart, using C# and winform. With the source code below, I was able to make it show real-time values, whenever an event occurs and it gets a new value(3~5 times a second). valueArray continuously gets new values through GetRealTimeData function and the chart shows all the elements in the array. valueArray[valueArray.Length - 1] = Convert.ToDouble(GetRealTimeData().Trim()); Array.Copy

问题 I am looking for a way to do a (actually quite common) visualization, whereby the split of a population of, say, N units into several categories is shown via a set of N pictograms - I'd prefer filled squares; in a newspaper, etc., one might see little humanoid shapes - with each pictogram colored according to the category of n'th unit. N fixed to 1 or 100, and the chart displaying fractions or percentages rather than counts, would be OK. The colored "stripes" would have to wrap to multiple
