Where Is The Serial Number On Msa Altair 4x

[Juanjo Pollreisz]

Thebasic data model used by Altair is tabular data,similar to a spreadsheet or database table.Individual datasets are assumed to contain a collection of records (rows),which may contain any number of named data fields (columns).Each top-level chart object (i.e. Chart, LayerChart,VConcatChart, HConcatChart, RepeatChart,and FacetChart) accepts a dataset as its first argument.

When data is specified as a pandas DataFrame, Altairuses the data type information provided by pandas to automatically determinethe data types required in the encoding. For example, here we specify data via a pandas DataFrameand Altair automatically detects that the x-column should be visualized on a categorical (nominal) scaleand that the y-column should be visualized on a quantitative scale:

By comparison,all other ways of specifying the data (including non-pandas DataFrames)requires encoding types to be declared explicitly.Here we create the same chart as above using a Data object,with the data specified as a JSON-style list of records:

Notice the extra markup required in the encoding; because Altair cannot inferthe types within a Data object, we must specify them manually(here we use Encoding Shorthands to specify nominal (N) for xand quantitative (Q) for y; see Encoding Data Types).

There are two common conventions for storing data in a dataframe, sometimes calledlong-form and wide-form. Both are sensible patterns for storing data ina tabular format; briefly, the difference is this:

A concrete example will help in making this distinction more clear.Consider a dataset consisting of stock prices of several companies over time.The wide-form version of the data might be arranged as follows:

Notice here that each row contains a single observation (i.e. price), alongwith the metadata for this observation (the date and company name).Importantly, the column and index labels no longer contain any useful metadata.

If you would like to convert data from wide-form to long-form, there are two possibleapproaches: it can be done as a preprocessing step using pandas, or as a transformstep within the chart itself. We will detail to two approaches below.

For converting wide-form data to the long-form data used by Altair, the meltmethod of dataframes can be used. The first argument to melt is the columnor list of columns to treat as index variables; the remaining columns willbe combined into an indicator variable and a value variable whose names canbe optionally specified:

At times it is convenient to not use an external data source, but rather generate data fordisplay within the chart specification itself. The benefit is that the chart specificationcan be made much smaller for generated data than for embedded data.

It is convenient to use GeoPandas as the source for your spatial data.GeoPandas can read many types of spatial data and Altair works well with GeoDataFrames.Here we define four polygon geometries into aGeoDataFrame and visualize these using the mark_geoshape.

Since the spatial data in our example is not geographic,we use project configuration type="identity", reflectY=True to draw thegeometries without applying a geographic projection. By using alt.Color(...).scale(None) wedisable the automatic color assignment in Altairand instead directly use the provided Hex color codes.

If your source data is a GeoJSON file and you do not want to load itinto a GeoPandas GeoDataFrame you can provide it as a dictionary to the Altair Data class. AGeoJSON file normally consists of a FeatureCollection with a list offeatures where the information for each geometry is specified within aproperties dictionary. In the following example a GeoJSON-like dataobject is specified into a Data class using the propertyvalue of the key that contain the nested list (here namedfeatures).

The label for each objects location is stored within the properties dictionary. To access these valuesyou can specify a nested variable name (here properties.location) within the colorchannel encoding. Here we change the coloring encoding to be based on this location label,and apply a magma color scheme instead of the default one.The :O suffix indicates that we want Altair to treat these values as ordinal,and you can read more about it in the Encoding Data Types page.for the ordinal structured data.

Altair can load GeoJSON resources directly from a web URL. Here we usean example from geojson.xyz. As is explained in Inline GeoJSON Object,we specify features asthe value for the property parameter in the alt.DataFormat() objectand prepend the attribute we want to plot (continent)with the name of the nested dictionary where theinformation of each geometry is stored (properties).

TopoJSON is an extension of GeoJSON, where the geometry of the featuresare referred to from a top-level object named arcs. Each shared arc isonly stored once to reduce the size of the data. A TopoJSON file object can containmultiple objects (eg. boundary border and province border). Whendefining a TopoJSON object for Altair we specify the topojsondata format type and the name of the object we like to visualize using thefeature parameter. Here the name of this object key is MY_DATA,but this differs in each dataset.

Altair can load TopoJSON resources directly from a web URL. Asexplained in Inline TopoJSON Object, we have to use thefeature parameter to specify the object name (here boroughs) anddefine the type of data as topjoson in the alt.DataFormat() object.

We color encode the Boroughs by there names as they are stored as anunique identifier (id). We use a symbolLimit of 33 in twocolumns to display all entries in the legendand change the color scheme to have more distinct colors.We also add a tooltip which shows the name of the boroughas we hover over it with the mouse.

Similar to the feature option, there also exists the meshparameter. This parameter extracts a named TopoJSON object set.Unlike the feature option, the corresponding geo data is returned asa single, unified mesh instance, not as individual GeoJSON features.Extracting a mesh is useful for more efficiently drawing bordersor other geographic elements that you do not need to associate withspecific regions such as individual countries, states or counties.

GeoJSON data can also be nested within another dataset. In this case itis possible to use the shape encoding channel in combination with the:G suffix to visualize the nested features as GeoJSON objects.In the following example the GeoJSON object are nested within geoin the list of dictionaries:

LineString, Polygon and MultiPolygon geometries contain coordinates in an order: linesgo in a certain direction, and polygon rings do too. The GeoJSON-like structure of the__geo_interface__ recommends the right-hand rule winding order for Polygon andMultiPolygons. Meaning that the exterior rings should be counterclockwise and interiorrings are clockwise. While it recommends the right-hand rule winding order, it does notreject geometries that do not use the right-hand rule.

Altair does NOT follow the right-hand rule for geometries, but uses the left-hand rule.Meaning that exterior rings should be clockwise and interior rings should becounterclockwise.If you face a problem regarding winding order, try to force the left-hand rule on yourdata before usage in Altair using GeoPandas for example as such:

The S-100 bus also includes 8 interrupt signals. These are signals generatedby other devices when they need immediate attention from the CPU. Forexample (as we'll see later in this chapter), a keyboard mightgenerate an interrupt signal when a key is pressed. A short programrun by the 8080 can then determine what that key was and take someaction. The board containing the 8080 also generally includes a chipcalled the Intel 8214 Priority Interrupt Control Unit to handle theseinterrupts. When an interrupt occurs, this chip generates an interruptsignal to the 8080. When the 8080 acknowledges the interrupt, the chipprovides a RST (Restart) instruction that causes the microprocessor tosave the current program counter and branch to address 0000h, 0008h,0010h, 0018h, 0020h, 0028h, 0030h, or 0038h depending on theinterrupt.
