This page has details on all of the menu items on NZGrapher.
This menu area is about importing data into, and exporting data out of NZGrapher.
This allows you to open a file from your device. The file must be a csv. Excel files are not supported, you need to save it as a csv before uploading.
Import from Clipboard
This allows you to import data that you have already copied onto the clipboard. It needs to be copied from a table in a Google Sheet or an Excel Spreadsheet. The first time you try to use this function it will ask for access to the clipboard.
You need to press allow in order for this to work. If you press block, you can change the setting by pressing on the padlock icon and changing the toggle to on.
Paste Table (Legacy)
Some devices do not support import from clipboard. If this is the case, you can use the paste table (legacy) mode which allows you to paste in a table that you have copied from elsewhere. Note: this is slower than using the Import from Clipboard, so if you can use that, it is better.
This allows you to link to a csv file that is hosted on the internet.
Select and Copy Data Table
This highlights the data table and copies it to the clipboard. Useful if you want to take the data out into a report or a spreadsheet.
This downloads a copy of the data as a .csv
This downloads a copy of the data as well as all of the current settings as a .nzgrapher file. When you upload a .nzgrapher file it not only loads the data, but all the graph settings and displays that you had set up.
Save Current State for Reset
This sets the data in its current state as the "default" dataset, so when you press "reset" it resets back to this point.
This resets the data back to it's original state or back to where it was last time you pressed "Save Current State for Reset".
This adds a new row to the bottom of the dataset.
Delete Last Row
This removes the last row from the dataset.
Delete Last ___ Rows
Deletes the last x number of rows, gives you a prompt to ask how many rows you would like to remove.
Delete Specific Row
This deletes a specific row from the dataset (useful for removing outliers) by the point ID as shown on the left of the dataset.
Adds a column to the right of the dataset.
Delete Last Column
Deletes the rightmost column.
Delete Specific Column
Deletes a specific column.
Sample and More
Allows you to do either simple random samples, or stratified random samples.
This is also useful if you want to remove a particular section of the data... for example in the kiwi data set if you just wanted to look at GS and NiBr, you would set these to 163 and 275 respectively, and leave all the others blank and press sample.
Sorts the data table by a particular variable. This doesn't affect displays.
Allows you to prepend text (add to the start of) to a variable.
For example if you had a variable with values "N", "A", "M" and "E" and you wanted them to display in this order, you would put 1, 2, 3, 4 next to these respectively, and then it would graph in that order.
Create New Variable (From 2 Variables)
Allows you to add, subtract, multiply or divide two variables.
Create New Variable (Linear Function)
Allows you to create a new variable with an equation of y = m*x + c where x is one of the columns in the existing data set.
Create New Variable (Custom Function)
This allows you to create a new variable by putting in an algebraic function with x in in eg "1/x^2+3" and it will create a new variable from that function.
Create New Variable (From Condition)
Allows you to create "Low" or "High" variables. Conditions can be <, ≤, =, ≥, and >.
Create New Variable (Re-Group)
Allows you to regroup variables, for example if a variable has 5 groups, you can assign each group to a master group, so you have less overall groups.
Create New Variable (Average)
Creates a new variable by averaging columns.
Allows you to filter out numerical data, for example, only look at kiwis that weigh over 2kg.
Add Graphable Index Column
Adds a column to the start of the data that is just the id / index of the point.
Convert Time Column
Takes standard date / time fields and converts them to Seconds, Minutes, Hours or Days for graphing in scatter graphs or dot plots.
Encode Time Column
Encodes standard date / time fields into formats for use with the NZGrapher time series modules (eg: 2000M01)
Allows you to fix some of the axis start and end points as well as some other random settings.
Explains how to open up the menu on the right / bottom to show some of the extra tools in there.
For each of the teaching tools the best way to understand them is to watch the video tutorials.
This is for teaching how bootstrapping works.
This is for teaching what re-randomisation does.
This is for teaching the effects of sampling and the variability of sampling.
Takes you to this website with video tutorials on how to use the teaching tools.
Updates any manual changes you have made to the dataset to the graph and selection boxes at the bottom of the page.
Note: this doesn't permanently change the dataset saved on the server, it only saves changes while you are on the page.
Launches the display explorer which brings up a series of displays that you can make with the selected variables.
Takes you to this website with video tutorials on NZGrapher.
Takes you to this website with information on the different graphs NZGrapher can draw.
Takes you to this page.
Takes you to this website with information on the datasets pre-built into NZGrapher.
