trendline

问题 I am new to Pandas and Seaborn and trying to learn. I am trying to add a trend line and a bar plot on the same graph. I have some data that looks like Year Sample Size 2000 500 2001 3000 2003 10000 2004 20000 2004 23000 I am new to pandas and seaborn and I am attempting to draw a line through the bar plot showing a decreasing or an increasing trend but struggling to do it on the same graph. Till now, I have a bar plot. Below you can find the code. sampleSizes['Sample Size'] -> is the column I

问题 I have a dataset with user session numbers from my site which looks like: page_1 = [4,2,4,1,2,6,3,2,1,6,2,7,0,0,0] page_2 = [6,3,2,3,5,7,9,3,1,6,1,6,2,7,8] ... And so on. I would like to find out whether the page has a positive or negative trendline in terms of growth, however I would also like to get the pages that are growing/falling beyond a certain threshold. Python has a ton of solutions and libs for this kind of task, yet Ruby has only one gem (trendline) which has no code in it. Before

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 Assuming that I have the following values that I'm going to plot on a Line chart (these are values and not coordinates - the coordinates are calculated by my software and are shown below): [4,4,3,2,5,5] How would I turn those values into a set of trendline values/coordinates? (BTW I don't really have any Maths expertise beyond school level - so no fancy Maths terminology please!). To add further details: These are a set of values that are spaced equally across a 500 pixel space (an HTML5

问题 I am trying to plot multiple trend lines (every ten years) in a time series using ggplot. Here's the data: dat <- structure(list(YY = 1961:2010, a = c(98L, 76L, 83L, 89L, 120L, 107L, 83L, 83L, 92L, 104L, 98L, 91L, 81L, 69L, 86L, 76L, 85L, 86L, 70L, 81L, 77L, 89L, 60L, 80L, 94L, 66L, 77L, 85L, 77L, 80L, 79L, 79L, 65L, 70L, 80L, 87L, 84L, 67L, 106L, 129L, 95L, 79L, 67L, 105L, 118L, 85L, 86L, 103L, 97L, 106L)), .Names = c("YY", "a"), row.names = c(NA, -50L), class = "data.frame") Here's the

问题 So I've got some data stored as two lists, and plotted them using plot(datasetx, datasety) Then I set a trendline trend = polyfit(datasetx, datasety) trendx = [] trendy = [] for a in range(datasetx[0], (datasetx[-1]+1)): trendx.append(a) trendy.append(trend[0]*a**2 + trend[1]*a + trend[2]) plot(trendx, trendy) But I have a third list of data, which is the error in the original datasety. I'm fine with plotting the errorbars, but what I don't know is using this, how to find the error in the

问题 I am willing to plot 3 timeseries on the same chart. Datasource is a pandas.DataFrame() object, the type of Timestamp being datetime.date , and the 3 different time series drawn from the same column Value using the color argument of plotly.express.line() . The 3 lines show on the chart, but each one is accompanied by some sort of trendline. I can't see in the function signature how to disable those trendlines. Can you please help? I have made several attempts, e.g. using another color , but

问题 I can correctly plot a trendline with price data but the both X Y axis of date formatting is blank. I am not sure what is messing up this plot configuration for the axis.
