问题 I've created this D3 chart which displays the results sentiment value. However what I'm struggling to do is place an image next to the horizontal text. Using the JSFiddle as an example, lets say 'Result 2' is under 20%. There would be a sad face displayed to the right of the 'Result 2' text. Then if the value was higher than 20%... a happy face would be displayed instead. Is it possible to do this? JSFiddle: https://jsfiddle.net/sopjzwst/3/ I've created the 2 different faces below the chart

问题 I am implementing a multi-line series chart using d3.js and I am getting an error pointing to my x-axis when trying to plot my dateTime from the data coming in. "Error: attribute d: Expected number, "MNaN,376.88020650…"." Here is my function var data = [{ "Brand": "Toyota", "Count": 1800, "Time": "2017-04-02 16"}, { "Brand": "Toyota", "Count": 1172, "Time": "2017-04-02 17"}, { "Brand": "Toyota", "Count": 2000, "Time": "2017-04-02 18"}, { "Brand": "Honda", "Count": 8765, "Time": "2017-04-02 16

问题 I have problem with chartJS. I cannot add border around chart, yAxis unit title, and yAxis labelString with element. I'm using react with typescript. I can add only string to labelString. You can see what I want do do on screen and on another screen you can see what I actualy have. Is there any options in chart.js@2.7.1 to add these elements? First image is my goal. Second is actual. @edit This is my chartOptions file. I just pass arguments in function to get these options. import * as Chart

问题 Has anyone tried using date as a slider for Altair interactive scatter plots? I'm trying to reproduce a similar plot to the gapminder scatter: 1) Instead of a year filter I'm trying to use a date e.g. '2020-01-05' and having the follow error: altair.vegalite.v4.schema.core.BindRange->max, validating 'type' '2020-05-17T00:00:00' is not of type 'number' 2) When I try to parse it as an int, nothing shows up in the plot 3) Examples of using the Year slider: https://www.datacamp.com/community

问题 I'm trying to graph a set of data I have my y values as y=[129.000, 128.000, 140.000, 150.000] x=["1/2018", "2/2018", "3/2018", "4/2018"] # plot the data itself pylab.plot(x,y,‘o’) # calc the trendline (it is simply a linear fitting) z = numpy.polyfit(x, y, 1) p = numpy.poly1d(z) pylab.plot(x,p(x),“r–”) # the line equation: print “y=%.6fx+(%.6f)”%(z[0],z[1]) I keep getting: ufunc 'add' did not contain loop with signature matching type dtype ('S32') ('S32') ('S32') I have tried using epoch

问题 I want to plot a series of points (distance r, angle a, strength s) in a QPolarChart QPolarChart *chart = new QPolarChart(); ScatterSeries *series1 = new QScatterSeries(); series1->setMarkerSize(s); for(int i = 0; i < count; i++) { series1->setMarkerSize(s); // -> of course changes the marker size for the complete series series1->append(r, a); } chart->addSeries(series1); Now I want to make the marker size individual for each point, basically the size should represent the "strength" of each

问题 I am having a lot of difficulty using the statsmodels.formula.api function ols(formula,data).fit().rsquared_adj due to the nature of the names of my predictors. The predictors have numbers and spaces etc in them which it clearly doesn't like. I understand that I need to use something like patsy.builtins.Q So lets say my predictor would be weight.in.kg , it should be entered as follows: Q("weight.in.kg") so I need to take my formula from a list, and the difficulty arises in modifying every
