Power BI Visualization & R : 3D ScatterPlot with Interactive Rotation View by R Script Visual

 


In the video. I have shared the method on using R script visual with package scatterplot3d to generate a 3D scatter plot, and also introduce a way on adding dynamic viewing angles to  rotate the 3D plot with slicer visual based on power BI new parameter feature generated angle value table . In the demo we applied power query editor to prepare source data table for the 3D plot, used the R studio to cerate and edit R script for 3d scatter plot and finally adopt the slicer visual generate by Power BI new parameter for interactive rotating 3D graphic view angels dynamically. Hope the video give some helps for your power BI project developments. 



R Scripts:


# Load the scatterplot3d library:
library(scatterplot3d)

# Define variables from the source data for plotting:
x <- dataset$"Technical Skills"
y <- dataset$"Leadership & Management"
z <- dataset$"Personal Development"
l <- dataset$"Employee ID"

# apply scattedplot3d function to create the 3D scatter plot:
scatter3d <- scatterplot3d(x,y,z,
                           main = "3D Scatter Plot for Employee Skills Evaluations",
                           color = dataset$Index,
                           pch = 16,
                           type ="h",
                           xlab = "Tech Skills",
                           ylab = "Lead & Magt",
                           zlab = "Personal Devel",
                           angle = dataset$Angles[1],
                           cex.axis = 1.3,
                           col.axis = "darkgray",
                           cex.lab = 1.5,
                           col.lab = "darkblue"
                           )

# Convert 3D coordinates and add labels with colour to each employee point in the plot:
scatter3d.coords <- scatter3d$xyz.convert(x,y,z)
text(scatter3d.coords$x,
     scatter3d.coords$y,
     labels = l,
     cex =1,
     pos = 4,
     col = "blue")

Power BI DAX and Visualizations: Active employees across time (as x-axis) by Tenure group or age group

Image
Business Case raised by my youtube channel viewer on the 21st July 2023. In my employee tenure data, it has employee birthday, hire date and leaving date, and race, gender, etc. Do you have any idea how to create a dynamic measure of tenure and/or age, as well as a "tenure group" and "age group" that can change with the calendar date? I would like to show in a line chart the changing number of active employees across time (as x-axis). Furthermore, I would like to breakdown the number of employees by their age group or tenure group (using age group as a legend). The age or tenure group will be dynamically change according to the dates in the X-axis. Any suggestions are appreciated. My suggestions: Assumptions on what we have for the case:                         - an employee table with coloumns: table update(or registered) date,              ...

Excel VBA Tips: A Macro to Generate Line Chart Dynamically for Loan Schedule Trend Report

Image
The entire code shared in this video is designed to automate the process of creating a dynamic line chart based on loan data in the "Loan Report" sheet and display the chart on the "Charts" sheet. The chart shows trends in accumulated principal, accumulated interest, and loan remaining balance over time. The code is also flexible enough to handle both yearly and monthly loan schedule reports. The VBA codes as: Sub CreateLineChart()       '1. Variable Declarations     Dim srcSheet As Worksheet     Dim chtSheet As Worksheet     Dim lastRow As Long     Dim chartObj As Shape     Dim chartDataRange As Range     Dim xAxisRange As Range     Dim yAxisRange As Range     Dim colPrincipal As Variant     Dim colInterest As Variant     Dim colRemainingBalance, ColMonth As Variant     '2. set source and chart sheets     Set srcSheet = ThisWorkbook.Worksheets("Loa...
