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

问题 I have a problem with google charts. I have struggled with this problem for two few days now and I can't seem to find a solution. I'm suppose to create a monitoring system where I can see changing line chart that has two lines in it. I'm generating the data in the JS code (at least for now). I don't know what I'm doing wrong. I can make the chart visible with really simple static example but as soon as I'm trying to add some data to the chart it stops drawing. Error with this current version

问题 I have a bar chart built using Daniel Gindi iOS-charts. It represents history data over a period of time. The issue I am having is that the data is being plotted from left-to-right (new data -> old data). I need it to be plotted as right-to-left (old data -> new data). I know that I can reverse the order I input data into BarChartData , but then I have the issue of the chart still being left aligned. It needs to be right aligned. I found a discussion here talking about the issue of inverting

问题 I have been using HighCharts in my PHP website by migrating it from older charts and I am very impressed by the number of graph options and functions with this library. However I am not able provide hyperlinks to the values of the x-axis(or y-axis) in order to navigate to another URI. Code of Categories in this case xAxis: { categories: [ 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec' ] }, Can anyone point me to an example or documentation on Highcharts if

问题 I spent a day figuring this out but was unavailable to find a solution. Please if anyone can help. So I was making a cryptocurrency tracker in React. I managed to create a table displaying several currencies and also a column where I render Apexchart for various currencies based on the JSON data that's already saved with me in a javascript file i.e I'm not making any call to API to get the data. I already have static data with me. I just rendered the static data in the form of a table. Now

问题 What formula does Google Charts use to construct its histogram? For example, does it use Sturge's rule? Doane's rule? Scott's rule? etc. Is there any documentation on how it constructs it default bin size, min, and max? Here is a link to the Histogram page for Google Charts. Google Charts automatically chooses the number of bins for you. All bins are equal width and have a height proportional to the number of data points in the bin. In other respects, histograms are similar to column charts.
